UNLABELLED Metastasis is a complex, multistep process that begins with the epithelial-mesenchymal transition (EMT). Circulating tumor cells (CTC) are believed to have undergone EMT and thus lack or express low levels of epithelial markers commonly used for enrichment and/or detection of such cells. However, most current CTC detection methods target only EpCAM and/or cytokeratin (CK) to enrich e...
s 1. Discrete Poincaré Lemma (with M. Desbrun, and J.E. Marsden) Appl. Numer. Math. 53 (2–4), 231–248, 2005. This paper proves a discrete analogue of the Poincaré lemma in the context of a discrete exterior calculus based on simplicial cochains. The proof requires the construction of a generalized cone operator, p : Ck(K)→ Ck+1(K), as the geometric cone of a simplex cannot, in general, be inter...
We study the complexity of data disjunctions in disjunctive deductive databases (DDDBs), i.e., minimal clauses R( c1) _ _ R( ck), k 2, derived from the database in which all atoms involve the same predicate R. We consider deciding existence and uniqueness of a data disjunction, as well as actually computing one, both for propositional (data) and nonground (program) complexity of the database. O...
In the frame work of relativistic density functional theory, using full potential local orbital band structure scheme (FPLO), the magnetic properties of single 3d transition metals (3d-TM) adsorbed on 2D hexagonal boron nitride (2D h-BN) are investigated. Binding energies between 3d-TM adatoms and 2D h-BN in three different compositions, local spin magnetic moments of 3d-TM and total spin magne...
