Abstract

Das vorliegende Working Paper fasst die Ergebnisse des Teilprojektes „Bewohner*innenschaft und Migration“ zusammen, das Teil des BMBF-geförderten Verbundprojektes „Vom Stadtumbauschwerpunkt zum Einwanderungsquartier? (StadtumMig, Laufzeit 2019-2022, BMBF-FKZ 01UR1802C)“ war. Das Projekt untersuchte Ankommensprozesse von Geflüchteten in drei ostdeutschen Großwohnsiedlungen in Schwerin, Halle(Saale) und Cottbus seit 2014/15 und nahm dabei insbesondere Fragen des lokalen Zusammenlebens, des Ressourcenzugangs und der Bleibeperspektiven von Geflüchteten in den Blick., This working paper summarizes the results of the sub-project "Residents and Migration", which was part of the BMBF-funded joint project "From Demolition to Immigration? (StadtumMig, 2019-2022, BMBF-FKZ 01UR1802C)". The project examined the arrival processes of refugees in three large East German housing estates in Schwerin, Halle(Saale) and Cottbus since 2014/15, focusing in particular on questions of local coexistence, access to resources and the prospects for refugees to stay.

Abstract

Brain-computer interfaces (BCIs) have revolutionized the way humans interact with machines, particularly for patients with severe motor impairments. EEG-based BCIs have limited functionality due to the restricted pool of stimuli that they can distinguish, while those elaborating event-related potentials up to now employ paradigms that require the patient’s perception of the eliciting stimulus. In this work, we propose MIRACLE: a novel BCI system that combines functional data analysis and machine-learning techniques to decode patients’ minds from the elicited potentials. MIRACLE relies on a hierarchical ensemble classifier recognizing 10 different semantic categories of imagined stimuli. We validated MIRACLE on an extensive dataset collected from 20 volunteers, with both imagined and perceived stimuli, to compare the system performance on the two. Furthermore, we quantify the importance of each EEG channel in the decision-making process of the classifier, which can help reduce the number of electrodes required for data acquisition, enhancing patients’ comfort.

Abstract

The purpose of advanced Brain–Computer Interfaces (BCIs) is to connect the human brain with an external device without using the muscular system. To do this, they must effectively process mental activity and infer information on the users’ intentions and directives. This work proposes a novel and explainable BCI system capable of recognizing P300 deflection in single-trial EEGs with higher accuracy compared to the literature gold standard. Moreover, the proposed deep-learning approach allows us to go beyond the mere P300 detection, which is, to our best knowledge, the current state of the art. Indeed, we first identify the P300-related signal in the single-trial EEG signal, and then, we further discriminate the ERPs associated to the detected P300 between visual and auditory stimuli-related. To do this, we employ a CNN–LSTM neural network, which manages a 3D data representation of the acquired EEG signals. The performance of the approach is tested on experiments carried out on 22 subjects, revealing a 82.4% F1-score in P300 identification and 82.4% discriminating between visual and auditory stimuli. The employed algorithmic procedure also reports the most relevant each EEG channels in determining the predictions, adding interpretability to the proposed AI-based tools. These results pave the way for more sophisticated BCIs, capable of extending the set of available actions for the patients. The project was pre-approved by the Research Assessment Committee of the Department of Psychology (CRIP) for minimal risk projects, under the aegis of the Ethical Committee of University of Milano-Bicocca, on May 27th, 2019, protocol number RM-2019-193.

Abstract

Der Bericht gibt einen ��berblick ��ber die Ergebnisse des Projekts ���Nachbarschaften des Willkommens", das zwischen 2017 und 2021 die Bedingungen f��r sozialen Zusammenhalt in Nachbarschaften mit zunehmender Diversit��t durch Fluchtmigration erforscht hat. Dabei ging das Projekt der Frage nach, wo Vorstellungen und Praktiken des sozialen Zusammenhalts vorherrschen, die auch neue Bewohner_innen und Nutzer_innen mit Fluchthintergrund inkludieren, und wo dies nicht der Fall ist. In diesem Kontext fragte das Projekt insbesondere danach, wo Gefl��chtete, die im Quartier wohnen oder es nutzen, Zug��nge zu zentralen Res- sourcen wie Wohnraum, Unterst��tzung, Teilhabe und Mitbestimmung erhalten und wie diese Zug��nge lokal ausgehandelt, entschieden und gelebt werden. Diese Fragen wurden in vier Nachbarschaften untersucht, die unterschiedliche sozio��konomische Zusammensetzungen so- wie unterschiedlich ausgepr��gte Migrationsgeschichten aufweisen., The report provides an overview of the results of the project Nachbarschaften des Willkommens (���Welcoming Neighbourhoods���), which from 2017 to 2021 researched the conditions of social cohesion in neighbourhoods with increasing diversity due to refugee migration. In doing so, the project explored the question of where ideas and practices of social cohesion that include new refugee residents and users prevail, and where this is not the case. In this context, a leading research question was where refugees living in or using a neighbourhood gain access to key resources such as housing, support, and participation, and how access to these resources is negotiated, decided, and lived locally. These questions were studied in four neighbourhoods which have different socio-economic compositions and migration histories.

Abstract

Context. Until recently, camera networks designed for monitoring fireballs worldwide were not fully automated, implying that in case of a meteorite fall, the recovery campaign was rarely immediate. This was an important limiting factor as the most fragile - hence precious - meteorites must be recovered rapidly to avoid their alteration. Aims. The Fireball Recovery and InterPlanetary Observation Network (FRIPON) scientific project was designed to overcome this limitation. This network comprises a fully automated camera and radio network deployed over a significant fraction of western Europe and a small fraction of Canada. As of today, it consists of 150 cameras and 25 European radio receivers and covers an area of about 1.5 × 10km. Methods. The FRIPON network, fully operational since 2018, has been monitoring meteoroid entries since 2016, thereby allowing the characterization of their dynamical and physical properties. In addition, the level of automation of the network makes it possible to trigger a meteorite recovery campaign only a few hours after it reaches the surface of the Earth. Recovery campaigns are only organized for meteorites with final masses estimated of at least 500 g, which is about one event per year in France. No recovery campaign is organized in the case of smaller final masses on the order of 50 to 100 g, which happens about three times a year; instead, the information is delivered to the local media so that it can reach the inhabitants living in the vicinity of the fall. Results. Nearly 4000 meteoroids have been detected so far and characterized by FRIPON. The distribution of their orbits appears to be bimodal, with a cometary population and a main belt population. Sporadic meteors amount to about 55% of all meteors. A first estimate of the absolute meteoroid flux (mag < -5; meteoroid size ≥∼1 cm) amounts to 1250/yr/10km. This value is compatible with previous estimates. Finally, the first meteorite was recovered in Italy (Cavezzo, January 2020) thanks to the PRISMA network, a component of the FRIPON science project., FRIPON was initiated by funding from ANR (grant N.13- BS05-0009-03), carried by the Paris Observatory, Muséum National d’Histoire Naturelle, Paris-Saclay University and Institut Pythéas (LAM-CEREGE). VigieCiel was part of the 65 Millions d’Observateurs project, carried by the Muséum National d’Histoire Naturelle and funded by the French Investissements d’Avenir program. FRIPON data are hosted and processed at Institut Pythéas SIP (Service Informatique Pythéas), and a mirror is hosted at IMCCE (Institut de Mécanique Céleste et de Calcul des Éphémérides / Paris Observatory) with the help of IDOC (https://idoc.ias.u-psud.fr) (Integrated Data and Operation Center), supported by CNRS and CNES. PRISMA is the Italian Network for Systematic surveillance of Meteors and Atmosphere. It is a collaboration initiated and coordinated by the Italian National Institute for Astrophysics (INAF) that counts members among research institutes, associations and schools (http://www.prisma.inaf.it). PRISMA was partially funded by 2016 and 2020 Research and Education grants from Fondazione Cassa di Risparmio di Torino and by a 2016 grant from Fondazione Agostino De Mari (Savona). FRIPON-Bilbao is supported by a grant from Diputacion Foral Bizkaia (DFB/BFA). FRIPONMOROI was supported by a grant of the Romanian Ministery of Research and Innovation, CCCDI - UEFISCDI, project number PN-III-P1-1.2-PCCDI2017-0226/16PCCDI/2018 , within PNCDI III. Rio de Janeiro camera is hosted and partially maintained by MAST (Museum of Astronomy and Related Sciences)/MCTIC.

Author

Rennie, Leoni J.

Abstract

Reports a study examining the relationship between affect and achievement for grade eight students in Australia (n=390). It was found that affect is related more strongly to previous than subsequent achievement and that much of the common variance can be attributed to students' perceptions of their competence in science.

14. Internal migration industries: Shaping the housing options for refugees at the local level

Abstract

In this article, we focus on ways in which ‘internal migration industries’ shape the housing location of refugees in cities. Based on empirical studies in Halle, Schwerin, Berlin, Stuttgart and Dresden, we bring two issues together. First, we show how a specific financialised accumulation model of renting out privatised public housing stock to disadvantaged parts of the population has emerged that increasingly targets migrant tenants. With the growing immigration of refugees to Germany since 2015, this model has intensified. Second, we discuss how access to housing is formed by informal agents. While housing is almost inaccessible for households on social welfare, the situation is even worse for refugees. This situation has given rise to a new ‘shadow economy’ for housing that offers services with dubious quality for excessive fees. Bringing these two issues together, we argue that housing provision to refugees has become a new business opportunity. This has given rise to a broad variety of ‘internal migration industries’ that provide the housing infrastructure, but also control access to housing. This not only results in new opportunities for profit extraction, but actively shapes new patterns of segregation and the concentration of refugees in particular types of disadvantaged neighbourhoods., Bundesministerium für Bildung und Forschung https://doi.org/10.13039/501100002347, bundesministerium für bildung und forschung https://doi.org/10.13039/501100002347

Abstract

This work presents a supervised machine-learning approach to build an expert system that provides support to the neuroscientist in automatically classifying ERP data and matching them with a multisensorial alphabet of stimuli. To do this, two different approaches are considered: a hierarchical tree-based algorithm, XGBoost, and feedfoward neural networks, highlighting the pros and cons of both approaches in the different steps of the classification task. Moreover, the sensitivity of the classification capabilities of the tool as a function of the number of available electrodes is also studied, highlighting what can be achieved by applying the method using commercial, wearable EEG systems. The main novelty of this work consists in significantly enlarging the pool of stimuli that the expert system can recognize and comprising different, possibly mixed, sensorial domains. The obtained results open the way to the design of portable devices for augmented communication systems, which can be of particular interest for the development of advanced Brain–Computer Interfaces (BCI) for communication with different types of neurologically impaired patients.

Abstract

Brain-computer interfaces (BCIs) are systems initially designed to compensate for motor disabilities affecting people whose control of the muscular system is compromised. However, recent developments open the BCIs market to a wide range of medical and non-medical applications. This raises the need for systems capable of interpreting more and more stimuli, even from different sensory domains. In this work, we design a machine-learning system able to fit both application domains accurately recognizing visual and auditory stimuli starting from the event-related potentials (ERPs) they generate. The obtained results are promising and some practical and realization aspects are discussed.

Abstract

The River Aniene, a left bank tributary of the River Tiber in Central Italy, is almost certainly affected by various industrial and urban sources of pollution, even if information on its characteristics within the city of Rome is poor or limited to a few elements. In order to awaken students from a high school specialized in science (Rocci High School in Passo Corese, in the province of Rieti) to this problem, in the framework of an "Alternanza scuola-lavoro" project conducted by CNR-IRSA, the water quality of the River Aniene was verified at two sampling points inside the city of Rome analysing a number of parameters foreseen in the Italian Decree 152/2006. In particular many physico-chemical parameters plus anions and metals were measured; moreover, some microbiological parameters, both those foreseen in Italian Decree 152/2006 (faecal contamination) and others (such as total microbial number and viability), were evaluated. The results showed widespread faecal contamination of the water sampled. Some values for chemicals were also not in accordance with the good quality water status standards foreseen in the Water Framework Directive (2000/60/EC) of the European Union and in the Italian Decree 152/2006. Among the various geo-genic and human activity elements influencing the water pollution the human ones were the most significant for the bad river water quality.

Abstract

Strong coupling in organic media holds the promise of efficient room temperature polariton lasing with solution-processed materials. Currently, however, only five pure-organic materials have been shown to demonstrate polariton lasing. A major challenge is to achieve high exciton–photon coupling while maintaining high photoluminescence quantum yield. Here, we utilize a series of diimide perylene materials that possess sterically hindered substituents, dispersed within a polymer matrix. The rigid structures prevent aggregation and allow high photoluminescence quantum yield (PLQY) at large dye loadings. We demonstrate that these systems can exhibit substantial Rabi splittings at dye loadings that yield film PLQYs of up to 85%, making these perylene derivatives promising materials for polariton lasers.

Abstract

INTRODUCTION: la glomérulonéphrite est une néphropathie fréquente dans la population pédiatrique et d’une gravité potentielle non négligeable. En effet, elle peut amener à l’insuffisance rénale chronique/terminale et compromettre ainsi le fonctionnement rénal des enfants atteints. Les glomérulonéphrites se présentent essentiellement par un syndrome néphritique, c’est-à-dire une protéinurie et une hématurie. A ce tableau clinique, en fonction du degré de l’atteinte glomérulaire, peuvent s’ajouter des symptômes aspécifiques tels que l’hypertension artérielle, les œdèmes et l’insuffisance rénale aiguë. BUT DU TRAVAIL ET MÉTHODOLOGIE : le but de ce travail est d’étudier les présentations cliniques et biologiques de la maladie au moment du diagnostic, ses complications ainsi que sa prise en charge dans un groupe de 48 enfants diagnostiqués pour une glomérulonéphrite au CHUV entre les années 2000 et 2014. L’identification des dossiers d’intérêt a été possible grâce aux dossiers codés aux archives médicales du Service de Néphrologie pédiatrique. Les données récoltées ont été ensuite analysées statistiquement et comparées aux résultats disponibles dans la littérature scientifique. Avant cette partie pratique, il a été nécessaire de procéder à une revue de la littérature (PubMed et UpToDate) afin de mieux connaître la maladie et sélectionner les articles pertinents pour ce travail. RÉSULTATS : dans notre étude, 92% des patients atteints d’une glomérulonéphrite sont d’origine caucasienne, 58% sont des garçons et la médiane d’âge est de 9 ans. La glomérulonéphrite la plus fréquente est la maladie de Berger (néphropathie à IgA chronique, 35%) et en deuxième position nous retrouvons la glomérulonéphrite aiguë post-infectieuse (31%). A noter que 27% de toutes les glomérulonéphrites présentaient un complément (C3/C4) abaissé tandis que 73% présentaient un complément normal. La glomérulonéphrite la plus retrouvée dans celles à complément abaissé est la glomérulonéphrite aiguë post-infectieuse (83%). En revanche, la maladie de Berger représente la majorité de celles à complément normal (61%). Au moment du diagnostic, 60% des patients présentaient une hématurie macroscopique et uniquement 8% un état général abaissé. 91% des patients présentaient une hématurie microscopique et la médiane de la protéinurie était à 2.08 g/L, avec une médiane pour le rapport protéines/créatinine urinaire à 200 g/mol. La médiane de la créatininémie était de 52.50 umol/L, celle de l’urémie à 5.70 mmol/L, cella de la protéinémie à 67.5 g/L et cella de l’albuminémie à 36 g/L. Les électrolytes étaient dans la majorité des cas dans les limites de la norme, avec une médiane de la natrémie à 138 mmol/L, de la kaliémie à 4.1 mmol/L, de la calcémie corrigée à 2.25 mmol/L et de la phosphatémie à 1.54 mmol/L. De plus, 14% des patients se trouvaient en acidose au moment du diagnostic. La médiane du débit de filtration glomérulaire au moment du diagnostic était de 92.66 ml/mn x 1.73m2 et 31% des patients étaient en insuffisance rénale au moment du diagnostic. Malgré cela, uniquement 2 patients sur 48 ont nécessité de dialyse et un seul patient a bénéficié d’une greffe rénale. Finalement, 7 patients sur 48 présentaient une insuffisance rénale chronique en fin de suivi pédiatrique. Enfin, 77% de nos patients ont nécessité d’une biopsie rénale à but diagnostic. Concernant la prise en charge, 73% des patients ont reçu des inhibiteurs du système rénine-angiotensine-aldostérone, 17% des inhibiteurs du récepteur à l’angiotensine II, 31% des corticoïdes et 19% des immunosuppresseurs autres (tels que azathioprine et mycophénolate mofétil). CONCLUSIONS : la glomérulonéphrite est une maladie fréquente qui nécessite donc une prise en charge rapide, spécialisée et adaptée au type de glomérulonéphrite et au degré d’atteinte glomérulaire. Lors de sa présentation initiale, la majorité des patients ont un état général conservé malgré la présence de plusieurs symptômes et signes cliniques tels que l’hématurie, souvent macroscopique, les œdèmes, et l’hypertension artérielle. Les différents examens de laboratoire permettent de mettre en évidence la protéinurie, l’hématurie et parfois une baisse de la protéinémie et de l’albuminémie, une augmentation de la créatiniémie, une augmentation de l’urémie, une acidose ou encore des troubles électrolytiques. Le diagnostic est surtout clinique en ce qui concerne les glomérulonéphrites aiguës post-infectieuses, en revanche il nécessite d’une biopsie rénale et une prise en charge spécialisée par les néphrologues pédiatres pour la majorité des autres formes.

Abstract

Sunlight, composed of different types of radiation, including ultraviolet wavelengths, is an essential source of light and warmth for life on earth but has strong negative effects on human health, such as promoting the malignant transformation of skin cells and suppressing the ability of the human immune system to efficiently detect and attack malignant cells. UV-induced immunosuppression has been extensively studied since it was first described by Dr. Kripke and Dr. Fisher in the late 1970s. However, skin exposure to sunlight has not only this and other unfavorable effects, for example, mutagenesis and carcinogenesis, but also a positive one: the induction of Vitamin D synthesis, which performs several roles within the immune system in addition to favoring bone homeostasis. The impact of low levels of UV exposure on the immune system has not been fully reported yet, but it bears interesting differences with the suppressive effect of high levels of UV radiation, as shown by some recent studies. The aim of this article is to put some ideas in perspective and pose some questions within the field of photoimmunology based on established and new information, which may lead to new experimental approaches and, eventually, to a better understanding of the effects of sunlight on the human immune system.

Abstract

Since 1993, Heavy Chain Antibodies (HCAbs) have been in the eye of a biotechnological storm. Ever since their discovery, several research groups as well as biomedical foundations and pharmaceutical companies have devoted their efforts to produce recombinant variable fragments (VHH) specific for therapeutic targets, based on HCAbs. They were supposed to be nonimmunogenic, and the smallest peptides with specific binding capacity and nanomolar affinity, and therefore expected to be an endless source of bio-drugs. In this context, a camelid-fever extended worldwide along with a sudden interest in breeding, selling and buying these animals. However, very few research groups showed interest in the health of these species, and even fewer in the immunobiological role of HCAbs in vivo. Why do these animals bear such proteins? Why has this feature only been found in camelids and cartilaginous fish? Is there any advantage in HCAbs when compared to conventional antibodies? This review is focused on the origin of the interest scientists had for HCAbs, and is aimed to understand the reasons for the generalized cooling-down of the HCAbs fever, and the sudden regained interest on camelids? health and immune system. We here review the history of HCAbs from their discovery to the current status of the knowledge about their immune system.

Abstract

In order to analyse the humoral immune response to the commensal yeast Pityrosporum ovale, we developed a western immunoblot technique with a salt soluble extract of P. ovale cytoplasm. In the present study, we tested sera from patients with psoriasis (n = 15), seborrhoeic dermatitis (n = 10), pityriasis versicolor (n = 8), and normal controls (n = 10). Seventy-three per cent (11/15) of the patients with psoriasis showed specific reactivity with a protein derived from P. ovale of estimated molecular mass 120 kDa, and 46% (7/15) of the cases recognized a 100-kDa protein. Sera from pityriasis versicolor and normal donors showed non-specific reactivity with several bands of lower molecular weight. To characterize the location of the 100 and 120-kDa proteins, we performed a lyticase digestion of the cell wall, and analysed the soluble digested products by western blotting. The sera from psoriasis patients detected several bands in the range 100-120 kDa. The finding of the immunoreactive 120-kDa protein in this fraction suggests its location at the space between cell wall and membrane (periplasmic space). As a control, we performed an extraction of the cytoplasmic proteins of the dimorphic yeast Candida albicans. C. albicans showed a different pattern of banding in SDS-PAGE. Immunoblots with C. albicans did not allow the detection of any related band. A smear was observed in the high molecular weight range consistent with the presence of lipopolysaccharides. The role of the immune response in infection by P. ovale has not yet been fully explored. The function of the antibodies recognizing 100-120-kDa bands in the majority of the patients with psoriasis seems to represent a specific immune response to the yeast phase of P. ovale.
