A disc-like heptanuclear Co(II)-cluster, [Co7(bzp)6(N3)9(CH3O)3].2ClO4.2H2O (1) (bzp = 2-benzoyl pyridine), mixed-bridged by 3/4 azides (mu1,1 and mu1,1,1) and 1/4 mu1,1,1-methanol, shows slow relaxation at static zero and non-zero fields below 6 K, towards single molecule magnet behavior.

The Energy Star certification program highlights energy efficient goods with a label. Given that it could either focus attention on the energy consumption of alternatives or provide a license to ignore the attribute, it follows that recent research highlights heterogeneity in consumers’ responses to the label. This paper answers two questions implied by this heterogeneity. First, do individuals...

We develop a convex approximation for two-stage mixed-integer recourse models and we derive an error bound for this approximation that depends on all total variations of the probability density functions of the random variables in the model. We show that the error bound converges to zero if all these total variations converge to zero. Our convex approximation is a generalization of the one in C...

This paper describes an experimental code that has been developed to solve zero one mixed integer linear programs The experimental code uses a primal dual interior point method to solve the linear programming subproblems that arise in the solution of mixed integer linear programs by the branch and bound method Computational results for a number of test problems are provided

Methods Data for this study was obtained from the web-based data of ISSC in 62 primary schools in two counties of Jiangxi province, China from April 1th, 2012 to June 30st, 2012. The ZIMM was used to explore: 1)the temporal and spatial variability regarding occurrence and intensity of absenteeism simultaneously, and 2) the heterogeneity among the reporting primary schools by introducing random ...

A novel dual-side mushroom ground plane (DMGP) structure is proposed for the noise suppression in high-speed multilayer printed circuit boards (PCBs). The proposed method is localized suppression technique where a dual-side mushroom structure is placed below the noise-sensitive device. In multilayer PCBs with DMGP, noise between two ports with large or small ports spacing can be minimized effec...
