The amalgamated duplication of a ring along a multiplicative-canonical ideal

After recalling briefly the main properties of the amalgamated duplication of a ring $R$ along an ideal $I$, denoted by R\JoinI, we restrict our attention to the study of the properties of R\JoinI, when $I$ is a multiplicative canonical ideal of $R$ \cite{hhp}. In particular, we study when every regular fractional ideal of $R\Join I$ is divisorial

Imitatio heroica

Unter dem Begriff der imitatio heroica lassen sich Formen des Auftretens und der Darstellung historischer Personen zusammenfassen, die sich heroische Figuren zum Vorbild nehmen. Seit der Antike gehört dies zu den häufigsten Formen vor allem, aber nicht nur der Bildnisrepräsentation politisch oder kulturell bedeutender Personen. Der Sammelband Imitatio heroica, Heldenangleichung im Bildnis widmet sich erstmals epochen- und disziplinenübergreifend diesem Phänomen. Dabei wird ein Zeitraum von der Antike bis zum 18. Jahrhundert in den Blick genommen. Ein grundsätzlicher Phänomenaufriss und Fallstudien aus den Bild- und Literaturwissenschaften machen die formalen und semantischen Grundlagen, Bedeutungen und historischen Tiefendimensionen der imitatio heroica anschaulich. In Heldenangleichungen wird das Heroische in seinen je historisch, medial und sozial bedingten Formen erkennbar, vor allem aber im Hinblick auf seine sinnliche Erfahrbarkeit das spezifische Potenzial visueller und habitueller Ausdrucksformen

Syndrome respiratoire aigu après inhalation de sprays imperméabilisants

Au cours de l'hiver 2002-2003, le Centre suisse d'information toxicologique a enregistré une augmentation inhabituelle de troubles respiratoires après exposition à des sprays imperméabilisants utilisés pour l'imprégnation du cuir et des textiles. Plus de 150 cas ont ainsi été rapportés. De telles épidémies sont déjà survenues au cours des vingt dernières années dans divers pays. Sur le plan clinique, des symptômes de toux, dyspnée et fièvre apparaissent dans le minutes ou les heures qui suivent l'exposition. Certains patients présentent une détresse respiratoire aiguë nécessitant une hospitalisation en soins intensifs. L'évolution clinique est favorable en quelques jours dans la majorité des cas, mais une dyspnée ou une toux chroniques pourraient persister chez certains patients. Un récent changement de formulation chimique semble être la cause de l'épidémie survenue en Suisse. Les produits incriminés ont été retirés de la vente. De nouveaux cas pourraient toutefois survenir à l'avenir en lien avec l'utilisation accrue de sprays imperméabilisants durant l'hiver et la possible commercialisation de nouveaux produits. [¨Résumé des Auteurs] A la suite de l'épidémie survenue en Suisse, l'Office fédéral de la santé publique a fait classer tous les sprays imperméabilisants pour cuirs et textiles dans la classe de toxicité 5S. Leurs emballages comporteront donc davantage d'avertissements aux utilisateurs. Il est actuellement recommandé d'employer ces sprays à l'air libre, d'éviter de s'exposer au brouillard de vaporisation (ne pas employer le spray contre le vent), et de bien laisser sécher les articles imperméabilisés à l'extérieur. L'emploi à l'intérieur est à éviter. Il ne suffit pas d'ouvir une fenêtre. Les personnes atteintes de maladies respiratoires (par exemple, asthme) devraient éviter d'utiliser elles-mêmes ces produits et ne pas se tenir à proximité d'un endroit où ils sont employés.

It is based on large survey answered by 14,000 participants in the bike to work action in Switzerland, and quantifies the various dimensions of utility cycling. It proposes an innovative theoretical framework to analyse and understand the various dimensions of the uses of bikes and their diversity. It addresses the factors that motivate commuters to get on their bike, and highlights the barriers to this practice between deficient infrastructures and lack of legitimacy. This research makes a diagnosis and discusses the way to develop this sustainable mode of transportation. By combining quantitative results in the form of tables, figures, and maps, and including qualitative results in the form of quotations from survey participants, this book provides a thorough and enjoyable read. It will be of interest to researchers, policy makers, advanced students in the field of urban planning, social sciences, and transportation

SAS CARE 1: Sleep architecture changes in a cohort of patients with Ischemic Stroke/TIA.

OBJECTIVE Changes in sleep architecture following ischemic stroke have been poorly investigated. Our objective was to explore changes of sleep structure in patients with ischemic stroke or transient ischemic attack in order to verify a possible predictive value of sleep with respect to clinical outcome. METHODS Patients recruited in the prospective SAS-CARE study received two polysomnographies (PSG) in the acute and chronic phases after stroke/TIA. Sleep parameters were compared between the two time-points and matched with a non-stroke population randomly selected from the HypnoLaus cohort. RESULTS Of the 169 patients investigated with PSG in the acute phase, 104 were again studied 3 months after stroke symptom onset and compared with 162 controls. The acute phase of stroke/TIA was associated with sleep disruption, which significantly improved in the chronic phase, but remained worse than controls (total sleep time improve from 318.8 ± 90.8 to 348.4 ± 81.5 min, compared to 388.2 ± 71.3 in controls, sleep latency from 49.9 ± 58.4 to 27.9 min, compared to 20.2 ± 22 in controls, sleep efficiency from 58.2 ± 18.1% to 27.9 ± 36.4 min, compared to 83.4 ± 10.3% in controls, wakefulness after sleep onset percentage from 36.5 ± 17.3 to 29.3 ± 15.6, compared to 13.2 ± 9.2 in controls). The percentage of REM sleep was negatively associated with stroke severity, whereas stroke topography did not correlate with sleep parameters. CONCLUSIONS This study confirmed a severe sleep disruption in the acute phase of stroke. Although a significant improvement of sleep quality was observed during the three months after stroke, sleep architecture did not normalize. In particular, sleep efficiency and REM sleep seem to be particularly affected by stroke in the acute phase, with a relative preservation of NREM sleep. We suggest that these sleep architecture changes represent a persistent marker of brain damage due to stroke. Further studies are needed to assess the relationship with stroke topographic and outcome

New distinguished classes of spectral spaces: a survey

In the present survey paper, we present several new classes of Hochster's spectral spaces "occurring in nature", actually in multiplicative ideal theory, and not linked to or realized in an explicit way by prime spectra of rings. The general setting is the space of the semistar operations (of finite type), endowed with a Zariski-like topology, which turns out to be a natural topological extension of the space of the overrings of an integral domain, endowed with a topology introduced by Zariski. One of the key tool is a recent characterization of spectral spaces, based on the ultrafilter topology, given in a paper by C. Finocchiaro in Comm. Algebra 2014. Several applications are also discussed

LAG3 is not expressed in human and murine neurons and does not modulate α-synucleinopathies.

While the initial pathology of Parkinson's disease and other α-synucleinopathies is often confined to circumscribed brain regions, it can spread and progressively affect adjacent and distant brain locales. This process may be controlled by cellular receptors of α-synuclein fibrils, one of which was proposed to be the LAG3 immune checkpoint molecule. Here, we analysed the expression pattern of LAG3 in human and mouse brains. Using a variety of methods and model systems, we found no evidence for LAG3 expression by neurons. While we confirmed that LAG3 interacts with α-synuclein fibrils, the specificity of this interaction appears limited. Moreover, overexpression of LAG3 in cultured human neural cells did not cause any worsening of α-synuclein pathology ex vivo. The overall survival of A53T α-synuclein transgenic mice was unaffected by LAG3 depletion, and the seeded induction of α-synuclein lesions in hippocampal slice cultures was unaffected by LAG3 knockout. These data suggest that the proposed role of LAG3 in the spreading of α-synucleinopathies is not universally valid

Three-Dimensional Imaging of the Mouse Neurovasculature with Magnetic Resonance Microscopy

Knowledge of the three-dimensional (3D) architecture of blood vessels in the brain is crucial because the progression of various neuropathologies ranging from Alzheimer's disease to brain tumors involves anomalous blood vessels. The challenges in obtaining such data from patients, in conjunction with development of mouse models of neuropathology, have made the murine brain indispensable for investigating disease induced neurovascular changes. Here we describe a novel method for “whole brain” 3D mapping of murine neurovasculature using magnetic resonance microscopy (μMRI). This approach preserves the vascular and white matter tract architecture, and can be combined with complementary MRI contrast mechanisms such as diffusion tensor imaging (DTI) to examine the interplay between the vasculature and white matter reorganization that often characterizes neuropathologies. Following validation with micro computed tomography (μCT) and optical microscopy, we demonstrate the utility of this method by: (i) combined 3D imaging of angiogenesis and white matter reorganization in both, invasive and non-invasive brain tumor models; (ii) characterizing the morphological heterogeneity of the vascular phenotype in the murine brain; and (iii) conducting “multi-scale” imaging of brain tumor angiogenesis, wherein we directly compared in vivo MRI blood volume measurements with ex vivo vasculature data
