Constant mean curvature hypersurfaces with constant δ-invariant
(Hindawi Publishing Corporation, 2003)
We completely classify constant mean curvature hypersurfaces (CMC) with constant
δ-invariant in the unit 4-sphere S4 and in the Euclidean 4-space E4.
Cohomologically Kähler manifolds with no Kähler metrics
(Hindawi Publishing Corporation, 2003)
We show some examples of compact symplectic solvmanifolds, of
dimension greater than four, which are cohomologically
Kähler and do not admit Kähler metric since their
fundamental groups cannot be the fundamental group ...
Global Self-Organization of the Cellular Metabolic Structure
(Public Library Science, 2008-08)
Background: Over many years, it has been assumed that enzymes work either in an isolated way, or organized in small catalytic groups. Several studies performed using "metabolic networks models'' are helping to understand ...
The Number of Catalytic Elements Is Crucial for the Emergence of Metabolic Cores
(Public Library of Science, 2009-10-19)
Background: Different studies show evidence that several unicellular organisms display a cellular metabolic structure characterized by a set of enzymes which are always in an active state (metabolic core), while the rest ...
