Scientists at Cornell and the American Museum of Natural History have identified 2,034 nearby star-systems – within the small cosmic distance of 326 light-years – that could find Earth merely by watch...
Having observed an m n matrix X whose rows are possibly correlated, we wish to test the hypothesis that the columns are independent of each other. Our motivation comes from microarray studies, where...
This paper is concerned with construction and structural analysis of both cyclic and quasi-cyclic codes, particularly LDPC codes. It consists of three parts. The first part shows that a cyclic code gi...
2001Vol.35No.5pp.585-588DOI: Electric Multipole Moments for Some First-Row Diatomic Hydride Molecules Metin Orbay and Telhat Özdoğan Department of Physics, Fac...
2003Vol.39No.2pp.223-224DOI: Response to “Comment on ‘Electric Multipole Moments for Some First-Row Diatomic Hydride Molecules’ [Commun. Theor. Phys. 38 (2002) 256]” Metin Orbay a...
This paper gives new algorithms for convex quadratic programming and linear programming. The algorithms mainly deal with nonconstrained maximization problems with simple concave objective functions. T...
All-electron variational and diffusion quantum Monte Carlo calculations of the ground state energies of the first row atoms (Li to Ne) are reported. We use trial wavefunctions of four types:single det...
