- Chamber measurements of trace gas fluxes between the land surface and the atmosphere have been conducted for almost a century. Different chamber techniques, including static and dynamic, have been used with varying degrees of success in estimating greenhouse gases (CO2, CH4, N2O) fluxes. However, all of these have certain disadvantages which have either prevented them from providing an adequate estimate of greenhouse gas exchange or restricted them to be used under limited conditions. Generally, chamber methods are relatively low in cost and simple to operate. In combination with the appropriate sample allocations, chamber methods are adaptable for a wide variety of studies from local to global spatial scales, and they are particularly well suited for in situ and laboratory-based studies. Consequently, chamber measurements will play an important role in the portfolio of the Pan-European long-term research infrastructure Integrated Carbon Observation System. The respective working group of the Integrated Carbon Observation System Ecosystem Monitoring Station Assembly has decided to ascertain standards and quality checks for automated and manual chamber systems instead of defining one or several standard systems provided by commercial manufacturers in order to define minimum requirements for chamber measurements. The defined requirements and recommendations related to chamber measurements are described here.

- Adaptation to the environment and extraction of energy are essential for survival. Some species have found niches and specialized in using a particular source of energy, whereas others-including humans and several other mammals-have developed a high degree of flexibility1. A lot is known about the general metabolic fates of different substrates but we still lack a detailed mechanistic understanding of how cells adapt in their use of basic nutrients2. Here we show that the closely related fasting/starvation-induced forkhead transcription factors FOXK1 and FOXK2 induce aerobic glycolysis by upregulating the enzymatic machinery required for this (for example, hexokinase-2, phosphofructokinase, pyruvate kinase, and lactate dehydrogenase), while at the same time suppressing further oxidation of pyruvate in the mitochondria by increasing the activity of pyruvate dehydrogenase kinases 1 and 4. Together with suppression of the catalytic subunit of pyruvate dehydrogenase phosphatase 1 this leads to increased phosphorylation of the E1α regulatory subunit of the pyruvate dehydrogenase complex, which in turn inhibits further oxidation of pyruvate in the mitochondria-instead, pyruvate is reduced to lactate. Suppression of FOXK1 and FOXK2 induce the opposite phenotype. Both in vitro and in vivo experiments, including studies of primary human cells, show how FOXK1 and/or FOXK2 are likely to act as important regulators that reprogram cellular metabolism to induce aerobic glycolysis.

- BACKGROUND AND AIMS: Social media use has become increasingly popular among Internet users. Given the widespread use of social media on smartphones, there is an increasing need for research examining the impact of the use of such technologies on sexual relationships and their constructs such as intimacy, satisfaction, and sexual function. However, little is known about the underlying mechanism why social media addiction impacts on sexual distress. This study investigated whether two constructs (intimacy and perceived social support) were mediators in the association of social media addiction and sexual distress among married women.METHODS: A prospective study was conducted where all participants (N = 938; mean age = 36.5 years) completed the Bergen Social Media Addiction Scale to assess social media addiction, the Female Sexual Distress Scale - Revised to assess sexual distress, the Unidimensional Relationship Closeness Scale to assess intimacy, and the Multidimensional Scale of Perceived Social Support to assess perceived social support.RESULTS: The results showed that social media addiction had direct and indirect (via intimacy and perceived social support) effects on sexual function and sexual distress.DISCUSSION AND CONCLUSIONS: The findings of this study facilitate a better understanding of how problematic engaging to social media can affect couples' intimacy, perceived social support, and constructs of sexual function. Consequently, sexual counseling should be considered an essential element for assessing individual behaviors in the context of social media use.

- Background and aim: Couples’ communication concerning sexual issues is influenced by various individual and social factors. The present study investigated the socio-demographic predictors of dyadic sexual communication among married women of reproductive age.Methods: A cross-sectional survey study was conducted from May to October 2019 in comprehensive health centers of Qazvin City, Iran. The participants comprised 400 married women with mean age of 35.66 years recruited via a two-stage sampling method. The Dyadic Sexual Communication Scale (DSCS) and a socio-demographic questionnaire were used for data collection. Univariable and multivariable linear regression models with a significance level of 0.05 were used for statistical analysis.Results: The mean score of sexual communication was 59.19 out of 78 (SD = 12.63). Based on multivariable linear regression model, life satisfaction (β = 0.34 high vs. moderate), frequency of sexual intercourse (β = 0.20), moderate vs. poor economic status (β = 0.12), and using contraception (β = −0.09) were predictors of good dyadic sexual communication. These variables explained 32% of the variance concerning dyadic sexual communication among married women of reproductive age.Conclusion: Life satisfaction, frequency of sexual intercourse, moderate economic status, and using contraception were predictors of good dyadic sexual communication.

Sleep patterns in school-age children with Asperger syndrome or high-functioning autism : A follow-up study

- The course of sleep patterns over 2-3 years was compared between 16 school-age children with Asperger syndrome (AS) or high-functioning autism (HFA) and 16 age- and gender-matched typically developing children, using 1-week actigraphy at baseline and follow-up. At baseline (mean age 11.1 years), children with AS/HFA had longer sleep latency and lower sleep efficiency during school days, but earlier sleep start and sleep end during weekends. At follow-up (mean age 13.7 years), children with AS/HFA had longer night wakings and lower sleep efficiency during weekends than the controls. The overall change of sleep patterns, however, is similar in children with AS/HFA and typically developing controls over a 2 to 3-year period.

The role and relevance of experimentation in informatics
- 2013

Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Informatics is a relatively young field within science and engineering. Its research and development methodologies build on the scientific and design methodologies in the classical areas, often with new elements to it. We take an in-depth look at one of the less well-understood methodologies in informatics, namely experimentation. What does it mean to do experiments in informatics? Does it make sense to ‘import’ traditional principles of experimentation from classical disciplines into the field of computing and information processing? How should experiments be documented? These are some of the questions that are treated. The report argues for the key role of empirical research and experimentation in contemporary Informatics. Many IT systems, large and small, can only be designed sensibly with the help of experiments. We recommend that professionals and students alike are well-educated in the principles of sound experimentation in Informatics. We also recommend that experimentation protocols are used and standardized as part of the experimental method in Informatics.
