BACKGROUND The majority of content in an Internet Support Group (ISG) is contributed by 1 % of the users ('super users'). Computational methods, such as topic modelling, can provide a large-scale quantitative objective description of this content. Such methods may provide a new perspective on the nature of engagement on ISGs including the role of super users and their possible effect on other u...

We explore the growth of super-massive black holes and host galaxy bulges in the galaxy population using the Millennium Run ΛCDM simulation coupled with a model of galaxy formation. We find that, if galaxy mergers are the primary drivers for both bulge and black hole growth, then in the simplest picture one should expect the mBH – mbulge relation to evolve with redshift, with a larger black hol...

BACKGROUND Despite achievement of universal health coverage in Thailand, socioeconomic inequality in health has been a major policy concern. This study examined mortality patterns across different socioeconomic strata in Thailand. METHODS We conducted a cross-sectional analysis of the 2010 Population and Housing Census on area-level socioeconomic deprivation against the 2010 mortality from th...

This paper provides computationally intensive, yet feasible methods for inference in a very general class of partially identified econometric models. The class of models we consider are those that are defined via a population objective function Q(θ, P ), which is not assumed to have a unique minimum in the parameter space Θ. The second argument P denotes the distribution of the observed data. T...

In the current multi-model ensemble approach climate model simulations are combined a posteriori. In the method of this study the models in the ensemble exchange information during simulations and learn from historical observations to combine their strengths into a best representation of the observed climate. The method is developed and tested in the context of small chaotic dynamical systems, ...

• Modelling suggests that blood type incompatibility may reduce the chance of transmitting SARS-CoV-2 by 60 % or more. Type O individuals are less likely to be infected, but “universal donors” and more spread infection. The risk A B depends upon which is frequent in population. Blood group frequencies partly explain different epidemic severity regions world. It important for ALL types vaccinate...

An Ising model on the kagome lattice with super-exchange interactions is solved exactly under the presence of a nonzero external magnetic field. The model generalizes the super-exchange model introduced by Fisher in 1960 and is analyzed in light of a free-fermion model. We deduce the critical condition and present detailed analyses of its thermodynamic and magnetic properties. The system is fou...

Supersonic random motions are observed in dark clouds and are traditionally interpreted as Alfvén waves, but the possibility that these motions are super-Alfvénic has

The voter model is one of the standard interacting particle systems. Two related problems for this process are to analyze its behavior, after large times t, for the sets of sites (a) sharing the same opinion as the site 0, and (b) having the opinion that was originally at 0. Results on the sizes of these sets were given in [Sa79] and [BG80]. Here, we investigate the spatial structure of these s...
