(MDPI AG, 2018-01-11)Obese children are usually less active than their normal-weight counterparts, although the reasons for this remain unclear. The objective of the present study was to determine how a long-term program (3 years of intervention and 6 months of follow-up ...
-
(Springer Nature, 2017-01-10)We study Coulomb interacting electrons confined in polygonal quantum rings. We focus on the interplay of localization at the polygon corners and Coulomb repulsion. Remarkably, the Coulomb repulsion allows the formation of in-gap states, i.e., ...

(Elsevier BV, 2020-04)We consider the Leader Election Problem in the Signal-to-Interference-plusNoise-Ratio (SINR) model where nodes can adjust their transmission power. We show that in this setting it is possible to elect a leader in two communication rounds, with high ...
-
(Frontiers Media SA, 2017-09-08)This study explored whether there is a gender difference in letter-sound knowledge when children start at school. 485 children aged 5-6 years completed assessment of letter-sound knowledge, i.e., large letters; sound of large letters; small letters; ...
-
(Elsevier BV, 2019-12)Background The Nordic countries have commonalities in gender equality, economy, welfare, and health care, but differ in culture and lifestyle, which might create country-wise health differences. This study compared life expectancy, disease ...
-
(SAGE Publications, 2020-01)Coronary artery disease is one of the most prevalent chronic pathologies in the modern world, leading to the deaths of thousands of people, both in the United States and in Europe. This article reports the use of data mining techniques to analyse a ...
-
(Elsevier, 2020-12)This study aimed to examine in a longitudinal cohort design whether social media use among adolescents is related to symptoms of social anxiety, depressed mood, and physical symptoms of anxiety over time. As part of the LIFECOURSE study of risk and ...
-
(Biomed Central LTD, 2013-06-19)Background: Achieving lifelong tobacco abstinence is an important public health goal. Most studies use 1-year follow-ups, but little is known about how good these are as proxies for long-term and life-long abstinence. Also, intervention intensity is ...
-
(Exeley, Inc., 2018)Background: Studies on early intervention have reported significant gains for many children with autism. Knowledge on how these children fare in adulthood is limited. Objective: To examine long-term outcome of children with autism who received ...
