Butterflies look like no other flying animal, with unusually short, broad and large wings relative to their body size. Previous studies have suggested butterflies use several unsteady aerodynamic mechanisms to boost force production with upstroke wing clap being a prominent feature. When the wings clap together at the end of upstroke the air between the wings is pressed out, creating a jet, pushin
In speech, the connection between sounds and word meanings is mostly arbitrary. However, among basic concepts of the vocabulary, several words can be shown to exhibit some degree of form–meaning resemblance, a feature labelled vocal iconicity. Vocal iconicity plays a role in first language acquisition and was likely prominent also in pre-historic language. However, an unsolved question is how voca
(1) Background: Although several neighborhood environmental factors have been identified to be associated with older adults’ physical activity, little research has been done in rural areas where the population is aging. This study aimed to investigate neighborhood environmental factors and the longitudinal change of physical activity status among rural older adults in Japan. (2) Meth-ods: The stud
In this paper non-overlapping domain decomposition methods for the pre-dual total variation minimization problem are introduced. Both parallel and sequential approaches are proposed for these methods for which convergence to a minimizer of the original problem is established. The associated subproblems are solved by a semi-smooth Newton method. Several numerical experiments are presented, which sh
Trust is one of the key factors that determines success or failure of any software project. However, achieving and maintaining trust in distributed software projects, when team members are geographically, temporally and culturally distant from each other, is a remarkable challenge. This paper explores the dynamics of trust and best practices performed in software organizations to address trust-rel
Morphometric relationships between populations of Papaver radicatum within the southern Norwegian mountains were investigated using canonical variates analysis and Ward's clustering on capsule and leaf character sets. The survey describes patterns of variation among 13 wild-scored populations from five geographically disjunct localities, usually assigned to five races or subspecies. Our results fr
Aims: Peripheral artery disease (PAD) constitute a high-risk with adverse clinical outcomes. We aimed to investigate the cardiovascular outcomes following myocardial infarction (MI). Methods and results: This nationwide, Danish register-based follow-up study includes all patients experiencing an MI between 2000 and 2017. Patients with and without PAD were compared. Multivariable logistic regressio
Background Premature ventricular complexes (PVCs) are generally quantified using a 24h ECG recording, but the diagnostic accuracy is unknown. We aimed to determine the day-to-day variability and optimal monitoring duration for PVC measurements among patients with frequent PVCs. Methods We included all patients who underwent a clinical ambulatory ECG recording lasting 25-30 days, using the PocketEC
At present, the prevalence of electric vehicles is increasing continuously. In particular, there are promising applications for commercial vehicles transfering from conventional to full electric, due to lower operating costs and stricter emission regulations. Thus, cost analysis from the fleet perspective becomes important. The study of cost competitiveness of different drivetrain designs is neces
The purpose of this study is to explore the inclusive involvement of non-R&D and non-managerial employees’ in processes of innovation. It answers a contemporary call for research to investigate a wider scope of organisations in the quest for understanding the interaction between employees and managers in employee-driven innovation (EDI). Based on a qualitative research study of two global corp
Wound infections are considered a major cause for wound-associated morbidity. There is a high demand for alternative, robust, and affordable methods that can provide relatable and repro-ducible results when testing topical treatments, both in research and in the pharmaceutical industry. Here we present an ex vivo wound infection model using porcine skin and a burn wounding method, allowing for the
Background: Visual snow syndrome (VSS) is a neurological condition characterized by flickering dots throughout the entire visual field. Both the pathophysiology and possible location of VSS are still under debate. White matter abnormalities were investigated using diffusion tensor imaging (DTI) in a patient with VSS. Methods: A 28-year-old patient with VSS and 10 healthy controls were investigated
Background: Information and communication technology (ICT) has been proven to have effect in terms of providing alternative ways to deliver rehabilitation services. The intention with this paper is to serve as a foundation for discussions regarding the future development, design, and delivery of home-based rehabilitation, including ICT. Aim: To reflect on and discuss the possibilities and challeng
A growing body of knowledge highlights the negative impact of the COVID-19 pandemic on the health and well-being of many people with intellectual and developmental disabilities (IDDs) and their caregivers. The underlying reasons are not only due to biomedical factors but also ethical issues. They stem from longstanding and pervasive structural injustices and negative social attitudes that continue
Background: Obesity is a growing health issue. This study estimated the costs of obesity among people aged 25–84 years in Sweden using disease and non-disease specific attributable fractions from published data. A prognosis of costs of obesity in 2030 is presented. Methods and materials: Diseases related to obesity and their respective risks and population attributable fraction were retrieved by l
