Technology Scaling Impact on Embedded ADC Design for Telecom Receivers
This paper is concerned with the impact of technology scaling on the choice of A/D converters in telecom receivers. It is shown that the trend of diminishing feature size, together with better matching of passive components, allows the use of A/D topologies traditionally confined to low-frequency, medium-resolution applications. The design of a 10 bit 20 MS/s ADC using the successive approximation algorithm is presented in order to validate the presented concepts. By using a deep-submicron technology, the speed of the chosen architecture is pushed to meet the desired output rate
BĂŒrgerwissenschaftliche ForschungsansĂ€tze in Medizin und Gesundheitsforschung: ausgewĂ€hlte Begriffe mit Fokus auf den Beteiligungsgrad
In den BĂŒrgerwissenschaften, auch bekannt unter dem englischen Begriff Citizen Science, existiert eine Vielzahl an ForschungsansĂ€tzen und Methoden. WĂ€hrend diese in vielen wissenschaftlichen Disziplinen gut etabliert sind, finden sich augenscheinlich relativ wenige davon in der medizinischen und Gesundheitsforschung. Allerdings zeigt ein Blick in die Praxis, dass bĂŒrgerwissenschaftliche AnsĂ€tze in der Medizin und Gesundheitsforschung durchaus praktiziert werden, jedoch hĂ€ufig unter anderen Namen. Der Artikel bietet aus interdisziplinĂ€rer Perspektive einen (selektiven) Ăberblick ĂŒber Begriffe, reflektiert diese und die dahinterstehenden Methoden und diskutiert sie vergleichend. Im Fokus steht dabei der Grad der Beteiligung der BĂŒrger*innen bzw. Patient*innen an wissenschaftlicher Forschung.In citizen science, a variety of research approaches and methods exist. While these are well established in many scientific disciplines, there are apparently relatively few of them in medical and health research. However, a glance at practice shows that citizen science approaches are indeed practiced in medical and health research, but often under different names. The paper therefore provides a (selective) overview of these terms, reflects on them and the methods behind them, and discusses them comparatively from an interdisciplinary perspective. The focus is on the degree of active participation of citizens and patients in research
Citizen scienceâs transformative impact on science, citizen empowerment and socio-political processes
Citizen science (CS) can foster transformative impact for science, citizen empowerment and socio-political processes. To unleash this impact, a clearer understanding of its current status and challenges for its development is needed. Using quantitative indicators developed in a collaborative stakeholder process, our study provides a comprehensive overview of the current status of CS in Germany, Austria and Switzerland. Our online survey with 340 responses focused on CS impact through (1) scientific practices, (2) participant learning and empowerment, and (3) socio-political processes. With regard to scientific impact, we found that data quality control is an established component of CS practice, while publication of CS data and results has not yet been achieved by all project coordinators (55%). Key benefits for citizen scientists were the experience of collective impact (âmaking a difference together with othersâ) as well as gaining new knowledge. For the citizen scientistsâ learning outcomes, different forms of social learning, such as systematic feedback or personal mentoring, were essential. While the majority of respondents attributed an important value to CS for decision-making, only few were confident that CS data were indeed utilized as evidence by decision-makers. Based on these results, we recommend (1) that project coordinators and researchers strengthen scientific impact by fostering data management and publications, (2) that project coordinators and citizen scientists enhance participant impact by promoting social learning opportunities and (3) that project initiators and CS networks foster socio-political impact through early engagement with decision-makers and alignment with ongoing policy processes. In this way, CS can evolve its transformative impact
ABCA3, a key player in neonatal respiratory transition and genetic disorders of the surfactant system
Genetic disorders of the surfactant system are rare diseases with a broad range of clinical manifestations, from fatal respiratory distress syndrome (RDS) in neonates to chronic interstitial lung disease (ILD) in children and adults. ABCA3 [ATP-binding cassette (ABC), subfamily A, member 3] is a lung-specific phospholipid transporter critical for intracellular surfactant synthesis and storage in lamellar bodies (LBs). Its expression is developmentally regulated, peaking prior to birth under the influence of steroids and transcription factors. Bi-allelic mutations of the ABCA3 gene represent the most frequent cause of congenital surfactant deficiency, indicating its critical role in lung function. Mutations affect surfactant lipid and protein processing and LBs' morphology, leading to partial or total surfactant deficiency. Approximately 200 mutations have been reported, most of which are unique to individuals and families, which makes diagnosis and prognosis challenging. Various types of mutations, affecting different domains of the protein, account in part for phenotype diversity. Disease-causing mutations have been reported in most coding and some non-coding regions of the gene, but tend to cluster in the first extracellular loop and the second nucleotide-binding domain (NBD), leading to defective glycosylation and trafficking defects and interfering with ATP binding and hydrolysis respectively. Mono-allelic damaging and benign variants are often subclinical but may act as disease modifiers in lung diseases such as RDS of prematurity or associate with mutations in other surfactant-related genes. Diagnosis is complex but essential and should combine pathology and ultrastructure studies on lung biopsy with broad-spectrum genetic testing of surfactant-related genes, made possible by recent technology advances in the massive parallel sequencing technology
