Heart rate variability and target organ damage in hypertensive patients
No full textBackground:
We evaluated the association between linear standard Heart Rate Variability (HRV) measures and vascular, renal and cardiac target organ damage (TOD).
Methods:
A retrospective analysis was performed including 200 patients registered in the Regione Campania network (aged 62.4 ± 12, male 64%). HRV analysis was performed by 24-h holter ECG. Renal damage was assessed by estimated glomerular filtration rate (eGFR), vascular damage by carotid intima-media thickness (IMT), and cardiac damage by left ventricular mass index.
Results:
Significantly lower values of the ratio of low to high frequency power (LF/HF) were found in the patients with moderate or severe eGFR (p-value < 0.001). Similarly, depressed values of indexes of the overall autonomic modulation on heart were found in patients with plaque compared to those with a normal IMT (p-value <0.05). These associations remained significant after adjustment for other factors known to contribute to the development of target organ damage, such as age. Moreover, depressed LF/HF was found also in patients with left ventricular hypertrophy but this association was not significant after adjustment for other factors.
Conclusions:
Depressed HRV appeared to be associated with vascular and renal TOD, suggesting the involvement of autonomic imbalance in the TOD. However, as the mechanisms by which abnormal autonomic balance may lead to TOD, and, particularly, to renal organ damage are not clearly known, further prospective studies with longitudinal design are needed to determine the association between HRV and the development of TOD
Neural correlates of processing valence and arousal in affective words
No full textPsychological frameworks conceptualize emotion along 2 dimensions, "valence" and "arousal." Arousal invokes a single axis of intensity increasing from neutral to maximally arousing. Valence can be described variously as a bipolar continuum, as independent positive and negative dimensions, or as hedonic value (distance from neutral). In this study, we used functional magnetic resonance imaging to characterize neural activity correlating with arousal and with distinct models of valence during presentation of affective word stimuli. Our results extend observations in the chemosensory domain suggesting a double dissociation in which subregions of orbitofrontal cortex process valence, whereas amygdala preferentially processes arousal. In addition, our data support the physiological validity of descriptions of valence along independent axes or as absolute distance from neutral but fail to support the validity of descriptions of valence along a bipolar continuum
Ett numinöst och programmerat kosmos : Religion och naturvetenskap i Peter Nilsons Projekt Nyaga
No full textA numinous and programmed cosmos: Religion and science in Peter Nilson’s Projekt Nyaga. By Mathias Persson. The purpose of the thesis has been to demonstrate one instance of interaction between popular science and science fiction. This demonstration has focused on the Swedish writer Peter Nilson, whose science fiction novels Nyaga and Rymdväktaren in many respects allude to his numerous essays on humanity and the universe. The thesis identifies four themes of a numinous character in the novels – one technological (omniscient super quantum computers), one mathematical or virtual (computer simulations of God), one evolutionary (god-like aliens), and one theistic (the design argument). When taken together, these not only indicate a harmonious relationship between science and religion, but between Nilson’s popular science and science fiction books as well. The contours of the world-view conveyed in Nyaga and Rymdväktaren are also traceable in the essays, which points to a coherent and enduring conception of reality on behalf of the author. Even if Nilson’s adherence to the modern, cosmology-based design argument cannot be definitively proven, much of what he has written suggests his acceptance of a natural theology wherein the beauty, intricacy, and order of the cosmos combine to display the existence of a Grand Programmer. Hence, Nilson provides a computerisation of the universe insofar as he characterises it as a program or a programmed artefact, made intelligible and accessible primarily by sophisticated computers in the service of a reformed, technologically superior Catholic Church.</p

Impact of radio channel characteristics on the longitudinal behaviour of truck platoons in critical car-following situations
No full textTruck platooning is an application of cooperative adaptive cruise control (CACC) which relies on vehicle-to-vehicle communications facilitated by vehicle ad-hoc networks. Communication uncertainties can affect the performance of a CACC controller. Previous research has not considered the full spectrum of possible car-following scenarios needed to understand how the longitudinal behaviour of truck platoons would be affected by changes in the communication network. In this paper, we investigate the impact of radio channel parameters on the string stability and collision avoidance capabilities of a CACC controller governing the longitudinal behaviour of truck platoons in a majority of critical car-following situations. We develop and use a novel, sophisticated and open-source VANET simulator OTS-Artery, which brings microscopic traffic simulation, network simulation, and psychological concepts in a single environment, for our investigations. Our results indicate that string stability and safety of truck platoons are mostly affected in car-following situations where truck platoons accelerate from the standstill to the maximum speed and decelerate from the maximum speed down to the standstill. The findings suggest that string stability can be improved by increasing transmission power and lowering receiver sensitivity. However, the safety of truck platoons seems to be sensitive to the choice of the path loos model.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Transport and PlanningPolicy Analysi

Mergers and acquisitions in Germany: social setting and regulatory framework
No full textThe paper describes the legal and economic environment of mergers and acquisitions in Germany and explores barriers to obtaining and executing corporate control. Various cases are used to demonstrate that resistance by different stakeholders including minority shareholders, organized labour and the government may present powerful obstacles to takeovers in Germany. In spite of the overall convergence of European takeover and securities trading laws, Germany still shows many peculiarities that make its market for corporate control distinct from other countries. Concentrated share ownership, cross shareholdings and pyramidal ownership structures are frequent barriers to acquiring majority stakes. Codetermination laws, the supervisory board structure and supermajority requirements for important corporate decisions limit the execution of control by majority shareholders. Bidders that disregard the German preference for consensual solutions and the specific balance of powers will risk their takeover attempt be frustrated by opposing influence groups.
