We propose a new bi-clustering algorithm, LinCoh, for finding linear coherent bi-clusters in gene expression microarray data. Our method exploits a robust technique for identifying conditionally correlated genes, combined with an efficient density based search for clustering sample sets. Experimental results on both synthetic and real datasets demonstrated that LinCoh consistently finds more ac...
We present a coherent framework for data clustering. Starting with a Hopfield network, we show the solutions for several well-motivated clustering objective functions are principal components. For MinMaxCut objectives motivated for ensuring cluster balance, the solutions are the nonlinearly scaled principal components. Using scaled PC A, we generalize to multi-way clustering, constructing a sel...

background: 99mtc is a widely used radioisotope in nuclear medicine centers which is obtained by elution from mo-99/tc-99m generators. usually the generators are either supplied by the iran atomic energy agency or by private companies from foreign countries. in this study we have measured 99mo contamination in 99mtc elute from different generators in a period of one year. materials and methods:...
Neutrino-induced coherent charged pion production on nuclei νμA→μ(±)π(∓)A is a rare, inelastic interaction in which a small squared four-momentum |t| is transferred to the recoil nucleus, leaving it intact in the reaction. In the scintillator tracker of MINERvA, we remove events with evidence of particles from nuclear breakup and reconstruct |t| from the final-state pion and muon. We select low...
We demonstrate theoretically and experimentally the spontaneous clustering of solitons in partially coherent wavefronts during the final stages of pattern formation initiated by modulation instability and noise.
This paper presents the applications of hierarchical clustering to the generators in a power system. A useful application of fuzzy mathematics is that the correction of clustering results and determination of whether it can obtain correct transitive closure. Thus, the fuzzy transitive closure plays an important role in hierarchical clustering. Based on the fuzzy relation matrix, the hierarchica...
Detecting coherent and well-connected communities inside large-scale graphs is an interesting problem that can provide useful insight into the graph structure and individual communities. It can also serve as the basis for content exploration and discovery within the graph. Clustering is a popular technique for community detection, however, the two main categories of clustering algorithms, i.e, ...
