Constructing NSSD Molecular Graphs
A graph is said to be non-singular if it has no eigenvalue equal to zero; otherwise it is singular. Molecular graphs that are non-singular and also have the property that all subgraphs of them obtained by deleting a single vertex are themselves singular, known as NSSD graphs, are of importance in the theory of molecular π-electron conductors; NSSD = non-singular graph with a singular deck. Wher...
متن کاملA Qualitative Method to Construct Phase Portraits
We have developed and implemented in the QPORTRAIT program a qualitative simulation based method to construct phase portraits for a significant class of systems of two coupled first order autonomous differential equations, even in the presence of incomplete, qualitative knowledge. Differential equation models are important for reasoning about physical systems. The field of nonlinear dynamics ha...
متن کاملLearning to Construct Novel Structures
We investigate the problem of constructing novel representatives of a fixed but unknown concept over a structured, discrete domain, such as the set of unlabeled graphs. In particular, we consider an online scenario in which the learning algorithm immediately observes the true label of each proposed structure. This problem is highly relevant in many application domains and has so far been tackle...
متن کاملChlorophyll Fluorescence: A Novel Method to Screen for Herbicide Resistance
The susceptibility to Terbacil of six randomly selected strawberry cultivars (‘Aromas’, ‘Chambly’, ‘Harmonie’, ‘Kent’, ‘La Clé des Champs’ and ‘Seascape’) was analysed using chlorophyll florescence (CF) in comparison with visual observation, in an attempt to develop a method for use in a breeding programme to select herbicide-resistant strawberry lines. Terbacil was applied at one of five rates...
متن کاملCocktail δ-integration: a novel method to construct cellulolytic enzyme expression ratio-optimized yeast strains
BACKGROUND The filamentous fungus T. reesei effectively degrades cellulose and is known to produce various cellulolytic enzymes such as beta-glucosidase, endoglucanase, and cellobiohydrolase. The expression levels of each cellulase are controlled simultaneously, and their ratios and synergetic effects are important for effective cellulose degradation. However, in recombinant Saccharomyces cerev...
