Sugar beet (Beta vulgaris ssp. vulgaris) is a biennial, sucrose-storing plant, which is mainly cultivated as a spring crop and harvested in the vegetative stage before winter. For increasing beet yield, over-winter cultivation would be advantageous. However, bolting is induced after winter and drastically reduces yield. Thus, post-winter bolting control is essential for winter beet cultivation....

AMS classification : 35L65, 47H05 Abstract We show that Kruzhkov’s theory of entropy solutions to multidimensional scalar conservation laws [Kr] can be entirely recast in L and fits into the general theory of maximal monotone operators in Hilbert spaces. Our approach is based on a combination of level-set, kinetic and transport-collapse approximations, in the spirit of previous works by Giga, M...

Secondary to the increased survival following chemotherapy, brain metastases have recently become a significant clinical problem for breast cancer patients. The aim of this study was to characterize those functional phenotypes that might enhance brain metastasis in breast cancer cells. We first analyzed by two-dimensional electrophoresis (2DE-DIGE) differences in protein expression between pare...

The two proteins involved in the regulation of gas vesicle formation in Haloferax mediterranei, mcGvpE (activator) and mcGvpD (repressive function), are able to interact in vitro. It was also found that the respective proteins cGvpE and cGvpD of Halobacterium salinarum and the heterologous pairs mcGvpD-cGvpE and cGvpD-mcGvpE were able to interact. Previously constructed mcGvpD mutants with alte...

In this text we shall review the classification of foliations on complex projective surfaces according to their Kodaira dimension, following McQuillan’s seminal paper [MQ1] with some complements and variations given by [Br1] and [Br2]. Most of the proofs will be only sketched, and the text should be considered as guidelines to the above works (and related ones), with no exhaustivity nor selfcon...

Abstract: We provide, with proofs, a complete description of the authors’ construction of state-sum invariants announced in [CY], and its generalization to an arbitrary (artinian) semisimple tortile category. We also discuss the relationship of these invariants to generalizations of Broda’s surgery invariants [Br1,Br2] using techniques developed in the case of the semi-simple sub-quotient of Re...
