We study discrete two player all-pay auction with complete information. We provide full
characterization of mixed strategy Nash equilibria and show that they constitute a subset of Nash …

The conjecture that energy transport in sunspot penumbrae occurs through convection by an
interchange of magnetic flux tubes is used in order to construct a magnetostatic model for a …

Current sheet as a diagnostic for the subphotospheric structure of a SPOT ADS Classic is now
deprecated. It will be completely retired in October 2019. This page will automatically redirect to …

In this article, Svalbard was presented as place and object of intensive scientific research,
carried on under the rule of the 1920 Spitsbergen Treaty, which has transformed the …

This review describes global models of sunspots in overall magnetostatic equilibrium,
extending over many scale heights into the solar convection zone. Different explanations of the …

… We would like to thank the family of Professor Aleksander Kosiba and Dr Maria Jahn,
wife of professor Alfred Jahn, for the materials documenting the scientific effort of their close …

The results of computer simulations of the magnetic-field effects of starspots in late-type giants
(using the magnetic-spot models of Jahn and Stepien, 1984) are presented in tables and …

Liberated heat market works mainly like a liberated electric market in Nordic countries with
the exception that heat market works within a local district heating network. There are …

Data analysis workflows in many scientific domains have become increasingly complex and
flexible. Here we assess the effect of this flexibility on the results of functional magnetic …
