Exercise related sudden cardiac death (SCD) in the young — Pre-mortal characterization of a Swedish nationwide cohort, showing a decline in SCD among athletes

Aims: To study the frequency, etiology, and premortal abnormalities in exercise-related sudden cardiac death (SCD) in the young in Sweden. Methods: All subjects with SCD in 10–35-year olds in Sweden during 2000–10, were included (n = 514). Information about each case was retrieved from death certifications, autopsy- and medical records. The number of SCD in athletes was compared to national figure

Biomarker-based prognosis for people with mild cognitive impairment (ABIDE) : a modelling study

Background: Biomarker-based risk predictions of dementia in people with mild cognitive impairment are highly relevant for care planning and to select patients for treatment when disease-modifying drugs become available. We aimed to establish robust prediction models of disease progression in people at risk of dementia. Methods: In this modelling study, we included people with mild cognitive impair

Fabrication of Tunnel FETs demonstrating sub-thermal subthreshold slope

Tunnel Field Effect Transistor (TFET), based on band-to-band tunneling, overcomes the thermal limit (subthreshold slope (S) > 60 mV/decade) of the MOSFETs by filtering the high-energy Fermi tail, thereby allowing a substantial reduction of supply voltage and power consumption. Despite the steep slope behavior, TFETs can suffer from ambipolarity wherein carriers tunnel into the channel at both high

The hippocampus in families with schizophrenia in relation to obstetric complications

Background: Hippocampal volume reduction is a well replicated finding in schizophrenia. Evidence indicates a contribution of genetic and environmental factors, especially the influence of obstetric complications to this volume reduction. The aim of this study was to compare hippocampal volume of schizophrenic patients as well as and their relatives with control subjects and to quantify the additio

Integrated Transmitters for Cellular User Equipment–Wideband CMOS Power Amplifiers and Antenna Impedance Tuners

The digital cellular systems era started about thirty years ago with the release of the first digital cellphones. These first digital cellphones were very different from today’s slim and esthetic cellular pocket computers. They were not mass-produced in million units a day, and they were designed for radio performance rather than appearance. Today, all components are integrated inside the mobile p

An organizational study into the concept of automation in a safety critical socio-technical system

Although automation has been introduced in all areas of public life, what seems to be missing is a reflection at the organizational or societal level about a policy of automation. By this we intend appropriate declarations made at the level of rationale, future plans and strategies to achieve intended goals and most importantly how those achievements will impact on various aspects of societal life

An organizational study into the concept of "automation policy" in a safety critical socio-technical system

Although automation has been introduced in all areas of public life, what seems to be missing is a reflection at the organizational or societal level about a policy of automation. By this the authors intend appropriate declarations made at the level of rationale, future plans and strategies to achieve intended goals and most importantly how those achievements will impact on various aspects of soci

Exploring tags through videography

This article focuses on videography as a method for conducting research, as a means of communicating findings about tags and tagging to the public, and an opportunity to re-evaluate previously-collected empirical material.Based on ongoing explorative videographic research, the author discusses how the video medium can be used to go beyond the mere visual representation of tags as singular expressi

Wiki collaboration in organizations: an exploratory study

The use of social media technologies in organizations has introduced novel ways of collaboration, communication, and knowledge sharing. In this respect, the present study is concerned with examining the use of one type of social media, the wiki technology, by members of several professional communities of practice to collaborate and share knowledge with each other. As such, it seeks to identify an

Social media and organizing–An empirical analysis of the role of wiki affordances in organizing practices

The evolution of social media has introduced novel possibilities for work and interaction in organizations. The wiki technology is one important kind of social media technologies that is increasingly used to facilitate the creation and sharing of organizational knowledge within communities. Given the increasing use of social media in organizations and the lack of knowledge on their consequences fo

Quality-Elasticity: Improved Resource Utilization, Throughput, and Response Times Via Adjusting Output Quality to Current Operating Conditions

This work addresses two related problems for on-line services, namely poor resource utilization during regular operating conditions, and low throughput, long response times, or poor performance under periods of high system load. To address these problems, we introduce our notion of quality-elasticity as a manner of dynamically adapting response qualities from software services along a fine-grained

Association of Birth Weight With Type 2 Diabetes and Glycemic Traits: A Mendelian Randomization Study

Importance: Observational studies have shown associations of birth weight with type 2 diabetes (T2D) and glycemic traits, but it remains unclear whether these associations represent causal associations. Objective: To test the association of birth weight with T2D and glycemic traits using a mendelian randomization analysis. Design, Setting, and Participants: This mendelian randomization study used

The rate and perioperative mortality of caesarean section in Sierra Leone

Introduction Sierra Leone has the world's highest maternal mortality, partly due to low access to caesarean section. Limited data are available to guide improvement. In this study, we aimed to analyse the rate and mortality of caesarean sections in the country. Methods We conducted a retrospective study of all caesarean sections and all reported in-facility maternal deaths in Sierra Leone in 2016.

A miniature world in decline : European Red List of Mosses, Liverworts and Hornworts

AimThis Red List is a summary of the conservation status of the European species of mosses, liverworts and hornworts, collectively known as bryophytes, evaluated according to IUCN’s Guidelines for Application of IUCN Red List Criteria at Regional Level. It provides the first comprehensive, region-wide assessment of bryophytes and it identifies those species that are threatened with extinction at a

Clinical and angiographic outcomes of bioabsorbable vs. permanent polymer drug-eluting stents in Sweden : a report from the Swedish Coronary and Angioplasty Registry (SCAAR)

Aims: Randomized clinical trials have consistently demonstrated the non-inferiority of bioabsorbable polymer drug-eluting stents (BP-DES) with respect to DES having permanent polymers (PP-DES). To date, the comparative performance of BP- and PP-DES in the real world has not been extensively investigated. Methods and results: From October 2011 to June 2016, we analysed the outcomes associated with

Regional inhaled deposited dose of urban aerosols in an eastern Mediterranean city

We calculated the regional deposited dose of inhaled particulate matter based on number/mass concentrations in Amman, Jordan. The dose rate was the highest during exercising but was generally lower for females compared to males. The fine particles dose rate was 1010-1011 particles/h (101-102 μg/h). The PM10 dose rate was 49-439 μg/h for males and 36-381 μg/h for females. While resting, the PM10 de
