Materials and methods: Accuracy and

PSA : role in screening and monitoring patients with prostate cancer

The test used for early detection and monitoring of prostate cancer—prostate-specific antigen (PSA)—is one of the most accurate and frequently used tumor markers in medicine today. No tumor marker has had such a critical impact on early detection through stage-migration, and monitoring after treatment for prostate cancer as the blood test PSA. This chapter provides an overview of the PSA test and

Maps and stories in the creation of richer accounts of change in pastoral landscapes in Nordland, northern Norway

The categories and concepts in the existing official land-use maps have been under improvements over recent years; however, this study from Nordland, northern Norway, shows that they continue to pose several dilemmas when aiming to better capture the impacts of multiple land uses on reindeer herding. While these developments have done much to better communicate the presence of reindeer herding to

Exploring Different User Interfaces for Velocity based Training using Smart Gym Machines : Pilot Study

With the emerging technology called the Internet of Things (IoT), we can now connect computing devices and sensors to the Internet. The IoT sensors serve to collect data, pushing it and sharing it with a whole network of connected devices. We decided to explore how to utilize IoT data to increase the user experience from a commercial gym application called Advagym. Advagym is a commercial solution

Acceptability of a physiotherapeutic pain school treatment in trauma-affected populations in the Middle Eastern & Northern African region

Introduction: The aim of this study was to evalu-ate the acceptability of a physiotherapeutic pain treatment (Pain School), focusing on patient education, physical exercises and self-reliance, and a capacity building program developed for MENA based physiotherapists working with pain and trauma-affected populations. Method: Qualitative interviews with seven physiotherapists participating in the Pa

Probing porosity in metals by electrical conductivity : Nanoscale experiments and multiscale simulations

Motivated by the significant influence of the underlying microstructure on the effective electrical properties of a material system and the desire to monitor defect evolution through non-destructive electrical characterisation, this contribution is concerned with a detailed study of conductivity changes caused by the presence of sub-microscale pores. Reducing the complexity of the material system,

A prospective, controlled study on the utility of rotational thromboelastometry in surgery for acute type A aortic dissection

To evaluate the hemostatic system with ROTEM in patients undergoing surgery for acute type aortic dissection (ATAAD) using elective aortic procedures as controls. This was a prospective, controlled, observational study. The study was performed at a tertiary referral center and university hospital. Twenty-three patients with ATAAD were compared to 20 control patients undergoing elective surgery of

Average uranium bedrock concentration in Swedish municipalities predicts male lung cancer incidence rate when adjusted for smoking prevalence : Indication of a cumulative radon induced detriment?

Bedrock U has been used as a proxy for local indoor radon exposure. A preliminary assessment of cancer incidence rate in a cohort of 809,939 adult males living in 9 different Swedish counties in 1986 has been used to correlate the cumulative lung cancer and total cancer (excluding lung) incidence rates between 1986 and 2020, respectively with the municipality average value of bedrock U concentrati

Strategic communication in participatory culture : From one- and two-way communication to participatory communication through social media

In contemporary literature in strategic communication, public relations, and corporate communication, co-creation of meaning is often claimed to be a core objective (e.g., Coombs & Heath, 2006). The aim of this chapter is to review the literature on social media and strategic communication and develop arguments for why we believe the new communication structure is challenging old concepts and

The relation of body mass index, body height, and parity to pyelonephritis : A nationwide population-based cohort study of over one million parous women (1997-2018)

Objectives: We aimed to explore the association between various physiological factors and pyelonephritis in parous women. Methods: Swedish nationwide registers were used to identify 1,073,467 parous women aged 15-50 years. The study period began in 1997 and ended in 2018, or at the first incidence of pyelonephritis, death, or emigration. Cox proportional hazards methods were used to determine haza

Associations between metabolic factors and radiographic knee osteoarthritis in early disease - a cross-sectional study of individuals with knee pain

Objective: Metabolic factors have been shown to be associated to severe radiographic knee osteoarthritis (RKOA). However, more knowledge is needed in early clinical knee osteoarthritis (KOA). The aim was to study associations between metabolic factors and radiographic knee osteoarthritis (OA) in individuals with knee pain. A second aim was to study associations between metabolic factors and RKOA i

p-Basilica Groups

We consider a generalisation of the Basilica group to all odd primes: the p-Basilica groups acting on the p-adic tree. We show that the p-Basilica groups have the p-congruence subgroup property but not the congruence subgroup property nor the weak congruence subgroup property. This provides the first examples of weakly branch groups with such properties. In addition, the p-Basilica groups give the

En central del i detta arbete var att tillämpa och utvärdera den GIS-baserade GTCmodellen för beräkning av geografisk tillgänglighet för cykling i kommuner och tätorter av olika storlek (Robertson m.fl., 2018). Projektet har genomförts i samarbete med elva kommuner av olika storlek och struk

A physically active lifestyle is associated with lower long-term incidence of bipolar disorder in a population-based, large-scale study

Background: Physical activity has been proposed to be beneficial for the symptomatic control of bipolar disorder, but the duration of the effects, sex-specific mechanisms, and impact of exercise intensity are not known. Method: With an observational study design, we followed skiers and age and sex-matched non-skiers from the general population to investigate if participation in a long-distance cro

Phase Reassignment with Efficient Estimation of Phase Difference

The recently developed Matched Phase Reassignment (MPR) gives a time-frequency local measure of phase difference between short oscillatory transient signals. However, the resulting phase estimate is not satisfactory as it has poor resolution for high oscillatory frequencies. The MPR is also sensitive to high noise levels and is computationally cumbersome. In this paper, a novel reassignment method

Sensor node calibration in presence of a dominant reflective plane

Recent advances in simultaneous estimation of both receiver and sender positions in ad-hoc sensor networks have made it possible to automatically calibrate node positions - a prerequisite for many applications. In man-made environments there are often large planar reflective surfaces that give significant reverberations. In this paper, we study geometric problems of receiver-sender node calibratio

ROBUST PHASE DIFFERENCE ESTIMATION OF TRANSIENTS IN HIGH NOISE LEVELS

This paper presents the Reassignment Vector Phase Difference Estimator (RVPDE), which gives noise robust relative phase estimates of oscillating transient signals in high noise levels. Estimation of relative phase information between signals is of interest for direction of arrival estimation, source separation and spatio-temporal decoding in neurology as well as for soundscape analysis. The RVPDE
