A petri nets based design of cognitive radios using distributed signal processing

AbstractReconfigurability for transceivers for wireless access networks like Bluetooth, WiMAX and W-LAN will become increasingly important. An appropriately flexible and reliable software architecture, allowing the concurrent processing of different controlling tasks for wireless terminals will hence be an important asset. Already during the 1980s reconfigurable receivers were developed for radio intelligence in the short wave range and the concept of software radio (SR) was born. A software defined radio (SDR) is a practical version of an SR: The received signals are sampled after a suitable band selection filter, usually in the base band or a low intermediate frequency band. The signal processing in both SR and SDR requires a considerable amount of concurrent processes. Since Petri nets (PNs) are both simple and strong tools for the description and the design of such concurrent processes, it is recommendable to deploy them for SDR. SDRs have paved the way towards cognitive radios (CRs), which are based on SDRs that additionally sense their environments, track changes, and react upon their findings. A CR is an autonomous unit in a communications environment that frequently exchanges information with the networks it is able to access as well as with other CRs. In this communication, the authors will introduce a realization concept for a CR which forms the basis of a hardware/firmware demonstrator developed by the authors. This demonstrator makes use of a digital signal processor (DSP) which forms the core of the design and flexibly programmable hardware accelerators based on field programmable gate arrays (FPGAs). The authors will describe the solution also in view of the recent developments of IEEE 802.2

The power of names: radical identities in the Reformation Era

Book synopsis: This volume of essays explores the themes of radicalism and dissent within Protestantism. The comparisons highlight the contingent nature of particular settlements and narratives, and reveal the extent to which the definition of religious radicalism was dependent upon immediate context and show that radicalism and dissent were truly transnational phenomena. The historiography of the so-called radical reformation has been unduly shaped by the hostile categories imposed by mainstream or magisterial reformers during the sixteenth and seventeenth centuries. This volume argues that scholars should adopt an open-ended understanding of evangelical reform, and recognize that the boundaries between radicalism and its opposite were not always firmly drawn. The distinction between the two is an inheritance of the Lutheran Reformation of the 1520s, which shaped not only the later course of the Reformation in the Holy Roman Empire but also attitudes towards and writings on religious dissent in the Netherlands and England. Radical critique is immanent within mainstream Protestantism, in a faith that emphasizes the power of the gospel with its unrelenting demands

Nursing staff fluctuation and pathogenic burden in the NICU - effective outbreak management and the underestimated relevance of non-resistant strains

In the course of a hospital management takeover, a microbial outbreak took place in a tertiary neonatal intensive care unit (NICU). Here, we characterize the outbreak and its management. About 4 months prior to takeover, there was a sharp increase in positive isolates for MSSA and multidrug-resistant organisms (MDROs). Simultaneously, the nursing staff sick leave rate increased dramatically which directly correlated with the number of infection/colonization per week (r2 = 0.95, p = 0.02). During the following months we observed several peaks in positive isolates of methicillin-sensitive staphylococcus aureus (MSSA), MDROs and subsequently a vancomycin-resistant enterococcus (VRE) outbreak. Interventional outbreak management measures were only successful after substantial recruitment of additional nursing staff. None of the VRE, but 44% (n = 4) of MDRO and 32% (n = 23) of MSSA colonized infants developed symptomatic infections (p = 0.02). Among the latter, 35% suffered from serious consequences such as osteomyelitis. The most important risk factors for colonization-to-infection progression were low gestational age and birth weight. Nursing staff fluctuation poses a substantial risk for both bacterial colonization and infection in neonates. Comprehensive outbreak management measures are only successful if adequate nursing staff is available. Non resistant strains account for most neonatal infections – possibly due to their limited perception as being harmful

Physical, cognitive and emotional factors contributing to quality of life, functional health and participation in community dwelling in chronic kidney disease.

Quality of life (QoL) impairment is a well-known consequence of chronic kidney disease (CKD). The factors influencing QoL and late life functional health are poorly examined.Using questionnaires combined with neuropsychological examinations, we prospectively evaluated physical, cognitive, and emotional factors influencing QoL, functional health and participation in community dwelling in 119 patients with CKD stages 3-5 including hemodialysis (61.5±15.7years; 63% men) and 54 control patients of the same age without CKD but with similar cardiovascular risk profile.Compared with control patients, CKD patients showed impairment of the physical component of QoL and overall function, assessed by the SF-36 and LLFDI, whereas disability, assessed by LLFDI, was selectively impaired in CKD patients on hemodialysis. Multivariable linear regressions (forced entry) confirmed earlier findings that CKD stage (β = -0.24; p = 0.012) and depression (β = -0.30; p = 0.009) predicted the QoL physical component. Hitherto unknown, CKD stage (β = -0.23; p = 0.007), cognition (β = 0.20; p = 0.018), and depression (β = -0.51; <0.001) predicted disability assessed by the LLFDI, while age (β = -0.20; p = 0.023), male gender (B = 5.01; p = 0.004), CKD stage (β = -0.23; p = 0.005), stroke history (B = -9.00; p = 0.034), and depression (β = -0.41; p<0.001) predicted overall function. Interestingly, functional health deficits, cognitive disturbances, depression, and anxiety were evident almost only in CKD patients with coronary heart disease (found in 34.2% of CKD patients). The physical component of QoL and functional health decreased with age and depressive symptoms, and increased with cognitive abilities.In CKD, QoL, functional health, and participation in community dwelling are influenced by physical, cognitive, and emotional factors, most prominently in coronary heart disease patients

Cognitive Performance Is Highly Stable over a 2-Year-Follow-Up in Chronic Kidney Disease Patients in a Dedicated Medical Environment.

As kidney and brain functions decline with aging, chronic kidney disease (CKD) and dementia are becoming increasing health burdens worldwide. Among the risk factors for cognitive impairment, CKD is increasingly recognized. The precise impact of CKD on the development of cognitive impairment is poorly understood.In the New Tools for the Prevention of Cardiovascular Disease in Chronic Kidney Disease (NTCVD) cohort, which was recruited in a dedicated nephrology department, we examined the 2-year course of cognitive performance in 120 patients (73 patients with CKD stages 3-5D, 47 control patients without CKD with similar vascular risk profile) using a comprehensive battery of 10 neuropsychological tests.Kidney function, vascular risk factors and cognitive performance were highly stable both in CKD and control patients. The summary score of cognitive performance in CKD patients was very similar at baseline (z = -0.63±0.76) and follow-up (z = -0.54±0.79, p = 0.113), as was cognitive performance in control patients (z = -0.01±0.59 and 0.01±0.70, p = 0.862, at baseline and follow-up, respectively). Total serum cholesterol (199.6±36.0 and 186.0±32.9, p = 0.005 in controls; 194.4±46.1 and 181.2±41.2, p = 0.008 in CKD) and common carotid intima-media thickness (0.87±0.18 and 0.84±0.17, p = 0.351 in controls; 0.88±0.21 and 0.82±0.16, p = 0.002 in CKD) moderately but significantly decreased during the follow-up. In multivariable regression analyses, high age (β = -0.28, 95%CI = -0.48 to 0.08, p = 0.007) predicted decrease in cognitive performance.In this well-defined cohort receiving state-of-the-art therapy, cognitive performance did not decrease over 2 years. Our data emphasize the aspect of risk factor control, suggesting that dedicated medical care might prevent cognitive decline in CKD patients
