The Minimum Eccentricity Shortest Path Problem consists in finding a shortest path with minimum eccentricity given undirected graph. problem is known to be NP-complete and W[2]-hard respect the desired eccentricity. We present fpt-algorithms for parameterized by modular width, distance cluster graph, combination of treewidth eccentricity, maximum leaf number.

A novel procedure for estimating the relative importance of uncertain parameters of complex FE model is presented. The method is specifically directed toward problems involving high-dimensional input parameter spaces, as they are encountered during uncertainty analysis of large scale, refined FE-models. In these cases one is commonly faced with thousands of uncertain parameters and traditional ...

There is little experimental knowledge on the sequence dependent rate of hairpin formation in RNA. We have therefore designed RNA sequences that can fold into either of two mutually exclusive hairpins and have determined the ratio of folding of the two conformations, using structure probing. This folding ratio reflects their respective folding rates. Changing one of the two loop sequences from ...

Meta-theorems for polynomial (linear) kernels have been the subject of intensive research in parameterized complexity. Heretofore, there were meta-theorems for linear kernels on graphs of bounded genus, H-minor-free graphs, and H-topological-minor-free graphs. To the best of our knowledge, there are no known meta-theorems for kernels for any of the larger sparse graph classes: graphs of bounded...

This paper addresses some questions which have arisen from the use of the Sérsic r 1/n law in modelling the luminosity profiles of early type galaxies. The first issue deals with the trend between the half-light radius and the structural parameter n. We show that the correlation between these two parameters is not only real, but is a natural consequence from the previous relations found to exis...

The mammalian genome is organized into silenced and active domains, which are constituted by chromatin fibres. The fibres are comprised of nucleosome subunits in which nearly two turns of DNA wrap around a histone protein core. This first order of DNA structure is known as the 10 nm chromatin fibre. Almost since the discovery of the nucleosome our widely accepted paradigm of genome regulation h...

A three-dimensional finite element (FE) model for the prediction of mechanical properties of defect-free carbon nanotubes (CNTs) is developed by incorporating the modified Morse potential energy and the universal force field (UFF) with an analytical molecular structural model. The concept of the model is based on the assumption that CNTs, when loaded, behave like space-frame structures. Based o...

We present a novel approach to generating regional scale aboveground biomass estimates for tree species of the Lake Tahoe Basin using hyperspatial (<1 m ground resolution) remote sensing imagery. Tree crown shadows were identified and delineated as individual polygons. The area of shadowed vegetation for each tree was related to two tree structural parameters, diameter-at-breast height (DBH) an...

We present structural parameters for 204 stellar clusters in the Small Magellanic Cloud derived from fitting King and Elson, Fall, & Freeman model profiles to the V-band surface brightness profiles as measured from the Magellanic Clouds Photometric Survey images. Both King and EFF profiles are satisfactory fits to the majority of the profiles although King profiles are generally slightly superi...
