The eukaryotic transcription factor NF-Y consists of three subunits （A, B, and C）, which are encoded in Ara- bidopsis thaliana in multigene families consisting of 10, 13, and 13 genes, respectively. In principle, all potential combi- nations of the subunits are possible for the assembly of the heterotrimeric complex. We aimed at assessing the probability of each subunit to participate in the assembly of NF-Y. The evaluation of physical interactions among all members of the NF-Y subunit families indicate a strong requirement for NF-YB/NF-YC heterodimerization before the entire complex can be accomplished. By means of a modified yeast two-hybrid system assembly of all three subunits to a heterotrimeric complex was demonstrated. Using GFP fusion constructs, NF-YA and NF-YC localization in the nucleus was demonstrated, while NF- YB is solely imported into the nucleus as a NF-YC-associated heterodimer NF-YC. This piggyback transport of the two Arabidopsis subunits differs from the import of the NF-Y heterotrimer of heterotrophic organisms. Based on a peptide structure model of the histone-fold-motifs, disulfide bonding among intramolecular conserved cysteine residues of NF-YB, which is responsible for the redox-regulated assembly of NF-YB and NF-YC in human and Aspergillus nidulans, can be excluded for Arabidopsis NF-YB.

We prove an L∞ version of the Yan theorem and deduce from it a necessary condition for the absence of free lunches in a model of financial markets, in which asset prices are a continuous R^d valued process and only simple investment strategies are admissible. Our proof is based on a new separation theorem for convex sets of finitely additive measures.

Fundamental problems related to the high-speed combustion are analyzed. The result of plasma-chemical modeling is presented as a motivation of experimental activity. Numerical simulations of the effect of uniform non-equilibrium discharge on the premixed hydrogen and ethylene-air mixture in supersonic flow demonstrate an advantage of such a technique over a heating. Experimental results on multi-electrode non-uniform discharge maintenance behind wallstep and in cavity of supersonic flow are presented. The model test on hydrogen and ethylene ignition is demonstrated at direct fuel injection to low-temperature high-speed airflow.

The purpose of this article is to describe the development, components and properties of a publication indicator that the Ministry of Education and Culture in Finland uses for allocating direct core funding annually to universities. Since 2013, 13% of the core funding has been allocated on basis of publication indicator that, like the Norwegian model, is based on comprehensive national level publication data that is currently provided by the VIRTA publication information service. In 2015, the publication indicator was complemented with other components of the Norwegian model, namely, quality-weighted publication counts based on national Publication Forum authority list of the publication channels with ratings established by experts in the field. The funding model allocates around 1.6 billion euros annually to universities with the publication indicator annually distributing over 200 million euros. Besides the funding model, the indicator provides comparable data for monitoring the research performance of Finnish universities, fields and subunits. The indicator may also be used in the universities' local funding models and research management systems, sometimes even at individual level evaluation. Positive and negative effects of the indicator have been extensively discussed and speculated. Since 2011, the Finnish universities' productivity appears to have increased in terms of both quantity and quality of publications.
