Social forces connect individuals in different ways. When individuals get connected, one can observe distinguishable patterns in their connectivity networks. One such pattern is assortativity, also known as social similarity. Assortativity In networks with assortativity, similar nodes are connected to one another more often than dissimilar nodes. For instance, in social networks, a high similar...

Providing effective health interventions and achieving equity in health need to apply the community-based approaches such as social determinants of health. In the military organizations, these determinants have received less attention from the military health researchers and policymakers. Therefore, this study aimed to identify and explain the social determinants affecting the health of militar...

We present results from an independent analysis of friction that more generally addresses all crystalline materials by an extension of coincident site lattice theory and dislocation drag. Calculations for graphitic friction are carried out and agree in magnitude with experimental friction forces. More interestingly, static, dynamic and anisotropic friction forces, incommensurability effects and...

Fowler, N. 2017. Walking the Plank of the Entrepreneurial University. The little spin-out that could? Uppsala Dissertations from the Faculty of Science and Technology 130. 212 pp. Uppsala: Acta Universitatis Upsaliensis. ISBN 978-91-554-9800-9. Creating spinout companies (USOs) from university research is one focus of innovation policy. The phenomenon features in two main fields of enquiry: aca...

Global fits to precision cosmological data which show that there is a dark energy component comprising about 2/3 of the total cosmological energy also hint that a dark energy with w = P/ρ < −1 is viable, even favored. Here we discuss implications of such a surprising w, including whether it jeopardizes vacuum stability. It appears to be secure in microscopic processes, but why bulk dark energy ...

After a short review of the arguments for the existence of Particle Dark Matter in the Universe, I list the most plausible candidates provided by particle physics, i.e. neutrinos, axions, and WIMPs. In each case I briefly describe how to estimate the relic density, and discuss attempts at detecting these particles. At the end I discuss my personal favorite, the lightest supersymmetric particle,...
