Die Dissertation India Book House und die Comic-Serie Amar Chitra Katha (1970-2002) ist eine interdisziplinär angelegte Studie. Sie vermittelt Erkenntnisse über einen vernachlässigten Bereich der Mediengeschichte Indiens. Im ersten Teil wird das Modell "Kreislauf der Kultur" auf das Medienprodukt Amar Chitra Katha angewandt. Dabei werden fünf Prozesse berücksichtigt: Repräsentation, Produktion, Identität, Konsum und Regulierung. Im zweiten Teil werden ausgewählte ACK-Ausgaben aus den Kategorien Mythologie und Geschichte formal-inhaltlich analysiert und verglichen. Die jeweiligen Unterschiede in der Bearbeitungsform der ACK-Ausgaben werden auf die Erkenntnisse des ersten Teils bezogen. Dadurch konnten die arbeitsbedingten und verlagspolitischen Motive der Transformationen der ACK-Serie belegt werden.

Das kardiovaskuläre System stellt einen wesentlichen Grundbaustein des menschlichen Körpers dar. Insbesondere das Gewebe Blut und die damit verbundenen blutbildenden Komponenten sind in diesem Kontext Betrachtungspunkte für toxikologische Interaktionen. In diesem Dokument wird der Ansatz einer dreistufigen Wissensvermittlung zur Gewähr-leistung eines interdisziplinären Erkenntnisgewinns für das Blut sowie das blutbildende System angewendet. In der ersten Stufe werden die anatomischen s vorgestellt. Darauf aufbauend werden die Bestandteile des Blutes sowie dessen individuelle Eigenschaften erläutert. Anschließend werden Interaktionen ausgewählter toxischer Noxen diskutiert. Final werden ausgewählte Mechanismen dargestellt, um nutzerorientiert in geeignete Medienfunktionen des „Toxnetz-Explorers“ überführt zu werden

Neuromorphic systems take inspiration from the principles of biological information processing to form hardware platforms that enable the large-scale implementation of neural networks. The recent years have seen both advances in the theoretical aspects of spiking neural networks for their use in classification and control tasks and a progress in electrophysiological methods that is pushing the frontiers of intelligent neural interfacing and signal processing technologies. At the forefront of these new technologies, artificial and biological neural networks are tightly coupled, offering a novel “biohybrid” experimental framework for engineers and neurophysiologists. Indeed, biohybrid systems can constitute a new class of neuroprostheses opening important perspectives in the treatment of neurological disorders. Moreover, the use of biologically plausible learning rules allows forming an overall fault-tolerant system of co-developing subsystems. To identify opportunities and challenges in neuromorphic biohybrid systems, we discuss the field from the perspectives of neurobiology, computational neuroscience, and neuromorphic engineering.

Pulse wave velocity (PWV) and augmentation index (AI) are independent predictors of cardiovascular health. However, the comparability of multiple oscillometric modalities currently available for their assessment was not studied in detail. In the present study, we aimed to evaluate the relationship between indices of arterial stiffness assessed by diastolic and suprasystolic oscillometry. In total, 56 volunteers from the general population (23 males; median age 70 years [interquartile range: 65–72 years]) were recruited into observational feasibility study to evaluate the carotid-femoral/aortic PWV (cf/aoPWV), brachial-ankle PWV (baPWV), and AI assessed by 2 devices: Vicorder (VI) applying diastolic, right-sided oscillometry for the determination of all 3 indices, and Vascular explorer (VE) implementing single-point, suprasystolic brachial oscillometry (SSBO) pulse wave analysis for the assessment of cfPWV and AI. Within- and between-device correlations of measured parameters were analyzed. Furthermore, agreement of repeated measurements, intra- and inter-observer concordances were determined and compared for both devices. In VI, both baPWVand cfPWVinter-correlatedwell and showed good level of agreement with bilateral baPWVmeasured byVE (baPWV[VI]– baPWV[VE]R: overall concordance correlation coefficient [OCCC]¼0.484, mean difference¼1.94 m/s; cfPWV[VI]–baPWV[- VE]R: OCCC¼0.493, mean difference¼1.0m/s). In contrast, SSBO derived aortic PWA (cf/aoPWA[VE]) displayed only weak correlation with cfPWV(VI) (r¼0.196; P¼0.04) and ipsilateral baPWV (cf/ aoPWV[VE]R–baPWV[VE]R: r¼0.166; P¼0.08). cf/aoPWA(VE) correlated strongly with AI(VE) (right-sided: r¼0.725, P<0.001). AI exhibited marginal between-device agreement (right-sided: OCCC¼ 0.298, mean difference: 6.12%). All considered parameters showed good-to-excellent repeatability giving OCCC > 0.9 for 2-point-PWV modes and right-sided AI(VE). Intra- and inter-observer concordances were similarly high except for AI yielding a trend toward better reproducibility in VE (interobserver–OCCC[VI] vs [VE]¼0.774 vs 0.844; intraobserver OCCC[VI] vs [VE]¼0.613 vs 0.769). Both diastolic oscillometry-derived PWV modes, and AI measured either with VI or VE, are comparable and reliable alternatives for the assessment of arterial stiffness. Aortic PWV assessed by SSBO in VE is not related to the corresponding indices determined by traditional diastolic oscillometry.
