Society depends on services provided by critical infrastructures, and hence it is important that they are reliable and robust. Two main approaches for gaining knowledge required for designing and improving critical infrastructures are reliability analysis and vulnerability analysis. The former analyses the ability of the system to perform its intended function; the latter analyses its inability to

Colorectal cancer (CRC) is the third most common cancer globally, with approximately 1.2 million new cases every year. The highest incidence rates are seen in developed countries, thereby imposing dietary and lifestyle factors in the etiology of CRC. Accumulating epidemiological evidence suggests that obesity is a risk factor for CRC in particular in men, as weak or no associations are seen in wom

An active single balanced down-conversion mixer is implemented using InAs nanowire metal oxide semiconductor field effect transistors (MOSFETs) as both active devices and passive resistive loads. Circuits with 6 dB low-frequency voltage gain and a 3 dB bandwidth of 2 GHz are measured for a DC power consumption of 3.8 mW from a 1.5 V supply. The circuits are fabricated using contacts made with 12 μ

Objective: Lack of sensory feedback is a drawback in today's hand prostheses. We present here a non-invasive simple sensory feedback system, which provides the user of a prosthetic hand with sensory feedback on the arm stump. It is mediated by air in a closed loop system connecting silicone pads on the prosthetic hand with pads on the amputation stump. The silicone pads in a "tactile display" on

Recent high-visibility disasters have fueled public and political awareness of the importance of managing and mitigating their consequences effectively. In response, various countries have enacted legislation that demands the evaluation of emergency responses so that lessons for improvement can be learned. A series of field and experimental studies were conducted from 2005 to 2007 to assess the ab

Integration of III-V semiconductors on Si substrates allows for the realization of high-performance, low power III-V electronics on the Si-platform. In this work, we demonstrate the implementation of single balanced down-conversion mixer circuits, fabricated using vertically aligned InAs nanowire devices on Si. A thin, highly doped InAs buffer layer has been introduced to reduce the access resista

We sought to determine whether specific characteristics of vertebral fractures in elderly men are associated with low bone mineral density (BMD) and osteoporosis. Mister osteoporosis Sweden is a population based cohort study involving 3014 men aged 69 to 81 years. Of these, 1427 had readable lateral radiographs of the thoracic and lumbar spine. Total body (TB) BMD (g/cm²) and total right hip (TH)

We present comprehensive results on continuous atmospheric cluster and particle measurements in the size range similar to 1-42 nm within the European Integrated project on Aerosol Cloud Climate and Air Quality interactions (EUCAARI) project. We focused on characterizing the spatial and temporal variation of new particle formation events and relevant particle formation parameters across Europe. Dif

Abstract Objectives: The study aimed to test the construct validity, factor structure and reliability of the 11-item version of the Tampa Scale for Kinesiophobia (TSK-11, Swedish version) among older people (65+) with chronic pain. Design: Methodological study. Subjects: 433 participants with chronic pain (mean age 74.8, 65-98 years) completed postal questionnaires. 264 of the participants complet

This paper questions the correspondance between resilience engineering theory and the theoretical fundaments of traditional CRM training, with its related behavior assessments. Reviewing the theoretical roots of CRM it is concluded that such concepts are rather founded in the information processing paradigm hiding the complexities of adaption to rapidly changing situations. An alternative approach

Critical infrastructures provide indispensable services to society and extensive disruption of these give rise to large societal consequences. Most risk-related studies of critical infrastructures, however, focus rather narrowly on the direct consequences, e.g. expressed by services not supplied or cost of nonsupplied services. Although these measures might serve as a proxy for the direct societal

The society depends on reliable and robust services provided by technical infrastructures for its function. The impact of large-scale outages due to the inherent vulnerabilities of technical infrastructures has been demonstrated, for example, by the power outage in the U.S. in 2003 and the power outages in Sweden due to the storms Gudrun in January 2005 and Per in January 2007. Two of the main app

PURPOSE: To analyze the effect of germline mutations in BRCA1 and BRCA2 on mortality in patients with ovarian cancer up to 10 years after diagnosis.EXPERIMENTAL DESIGN: We used unpublished survival time data for 2,242 patients from two case-control studies and extended survival time data for 4,314 patients from previously reported studies. All participants had been screened for deleterious germlin

Critical infrastructures provide essential services which enable our society to function. Disruptions in infrastructures can have widespread effects, not only for the originating infrastructure but also, through mutual dependencies, for other infrastructures. Identifying vulnerabilities inherent in these system-of-systems is thus highly critical for the proactive management and avoidance of future

The performance of teams, with different levels of domain and crisis management experience, managing unexpected and escalating situations was observed using a mid-fidelity ship-bridge simulation and analysed by applying the central concepts of joint activity coordination as well as Woods’s theory building on data overload. The coordination strategies used by the teams were evaluated by applying coo

The aim of this work was to develop a model suited for detailed studies of aerosol dynamics, gas and particle phase chemistry within urban plumes, from local scale (1x1 km(2)) to regional scale. This article describes and evaluates the trajectory model for Aerosol Dynamics, gas and particle phase CHEMistry and radiative transfer (AD-CHEM). The model treats both vertical and horizontal dispersion p

Introduction: Specific coffee subtypes and tea may impact risk of pre- and post-menopausal breast cancer differently. We investigated the association between coffee (total, caffeinated, decaffeinated) and tea intake and risk of breast cancer. Methods: A total of 335,060 women participating in the European Prospective Investigation into Nutrition and Cancer (EPIC) Study, completed a dietary questio

To manage complex and dynamic socio-technical systems places demands on teams to deal with a range of more and less foreseeable situations. Three groups of participants with different maritime experiences were studied using the same simulation of a ship to better understand the role of generic competencies (e.g. information management, communication and coordination, decision making, and effect co

Reliable electrical power supply is a prerequisite for the modern society, and if it fails it can cause severe consequences in terms of economic losses and even fatalities. It is thus important to analyse the vulnerability of the electric power system. Network analysis has previously been used to analyse the vulnerability of electric transmission systems, however recent events in Sweden have shown
