Biomonitoring programs to access the ecological integrity of freshwaters tend to rely exclusively on structural parameters. Here we evaluated stream ecological integrity using (a) benthic macroinvertebrate derived metrics and a biotic index as measures of structural integrity and (b) oak litter decomposition and associated fungal sporulation rates as measures of functional integrity. The study ...

This paper presents a method for synthesizing multicomponent beam structural assemblies with maximum structural performance and manufacturability. The problem is posed as a relaxation of decomposition-based assembly synthesis, where both topology and decomposition of a structure are regarded as variables over a ground structure with nonoverlapping beams. A multiobjective genetic algorithm with ...

X-ray powder diffraction studies along with complementary Raman and infrared spectroscopy measurements disclosed the pressure-induced chemical decomposition of boric acid, H3BO3. The layered triclinic structure of H3BO3 suffers a highly anisotropic compression associated to a strong reduction of the interlayer spacing. The starting structure becomes unstable at about 2 GPa and decomposes on a c...

The problem is posed as a relaxation of decomposition-based assembly synthesis [1,2,3], where both topology and decomposition of a structure are regarded as variables over a ground structure with non-overlapping beams.

HoPLLS (Hierarchy of protein loop-lock structures) (http://leah.haifa.ac.il/~skogan/Apache/mydata1/main.html) is a web server that identifies closed loops-a structural basis for protein domain hierarchy. The server is based on the loop-and-lock theory for structural organisation of natural proteins. We describe this web server, the algorithms for the decomposition of a 3D protein into loops and...

Boolean functional decomposition techniques built on top of Shannon cofactoring are applied to obtain specialized 4-level forms called Projected Circuits, or P-circuits. We describe their minimization by heuristic and guaranteed approximation algorithms exploiting structural don’t care conditions, and prove properties for special cases about cost estimation and testability. A specific applicati...

Rank-width is a graph complexity measure that has many structural properties. It is known that the rank-width of an undirected graph is the maximum over all induced prime graphs with respect to split decomposition and an undirected graph has rank-width at most 1 if and only if it is a distance-hereditary graph. We are interested in an extension of these results to directed graphs. We give sever...
