Clustering has been one of the most popular approaches used in gene expression data analysis. A clustering method is typically used to partition genes according to their similarity of expression under different conditions. However, it is often the case that some genes behave similarly only on a subset of conditions and their behavior is uncorrelated over the rest of the conditions. As tradition...

We consider a methodology for the development and application of a class of generators that are externally parameterized tools enabling to generate Web component instances on demand depending on the context of use. Such generators are generalized entities of conventional Web components that indeed are lower-level generators for the portal domain. We use one-stage heterogeneous metaprogramming t...

We present a method for identifying the coherent structures associated with individual Lagrangian flow trajectories even where only sparse particle trajectory data are available. The method, based on techniques in spectral graph theory, uses the Coherent Structure Coloring vector and associated eigenvectors to analyze the distance in higher-dimensional eigenspace between a selected reference tr...

Sleep spindles are approximately 1 s bursts of 10-16 Hz activity that occur during stage 2 sleep. Spindles are highly synchronous across the cortex and thalamus in animals, and across the scalp in humans, implying correspondingly widespread and synchronized cortical generators. However, prior studies have noted occasional dissociations of the magnetoencephalogram (MEG) from the EEG during spind...

Transport barriers are ubiquitous generators of coherent patterns in complex dynamical systems. In recent years, significant advances have been made on the mathematics and computations of such barriers in temporally aperiodic flows. This special session surveys recent analytic and computational techniques for the identification of generalized transport barriers in dynamical systems, and reviews...

Even and odd q-deformed charge coherent states are constructed , their (over)completeness proved and their generation explored. A D-algebra realization of the SU q (1,1) generators is given in terms of them. They are shown to exhibit SU q (1,1) squeezing and two-mode q-antibunching, but neither one-mode, nor two-mode q-squeezing.

Clustering is an essential aid to human understanding. In its application to graphs, clustering allows a large graph to be partitioned into pieces that can be studied independently or collapsed to give a coarse picture. More importantly, it can be used to identify coherent subgraphs that bear particular attention. As the size of graphs under examination has continued to increase, it has become ...

An important problem in universal algebra consists in finding presentations of algebraic theories by generators and relations, which are as small as possible. Exhibiting lower bounds on the number of those generators and relations for a given theory is a difficult task because it a priori requires considering all possible sets of generators for a theory and no general method exists. In this art...
