In this research, the interaction of pyrimidine molecule with pristine B12N12 nanocluster is studied in different phases to understand the effect of environment on the electronic properties of the designated adsorption complexes. To this end, the pyrimidine adsorption over B12N12 in the gas phase and water medium is investigated using density functional theory (DFT) at the B97D/6-31+G(d,p) leve...

adsorption of cyanogen molecule on the surface of pristine and sc-doped b12n12 nanocage is scrutinized using at dft calculations to investigating its potential as chemical nanosensors. the results show that cyanogen is weakly adsorbed on the pristine b12n12 and consequently its electrical properties are changed insignificantly. in order to improve the properties of the nanocage sensor, sc dopin...

The problem considered here is that of determining whether a given spanning tree is a minimal spanning tree. In 1984, Komll os presented an algorithm which required only a linear number of comparisons, but nonlinear overhead to determine which comparisons to make. We simplify his algorithm and give a linear time procedure for its implementation in the unit cost RAM model. The procedure uses tab...

It is commonly appreciated that solving search problems optimally can take too long. Bounded suboptimal search algorithms trade increased solution cost in a principled way for reduced solving time. Explicit Estimation Search (EES) is a recent state-of-the-art algorithm for bounded suboptimal search. Although it tends to expand fewer nodes than alternative algorithms, its per-node expansion over...

In this paper, we analyze the performance of weighted 1 minimization over a non-uniform sparse signal model by extending the “Gaussian width” analysis proposed in [1]. Our results are consistent with those of [7] which are currently the best known ones. However, our methods are less computationally intensive and can be easily extended to signals which have more than two sparsity classes. Finall...

The abundant choices offered by digital media have raised concerns that audience behavior in news consumption might become polarized into people either aggressively seeking out or avoiding the news. Despite growing evidence to that effect, there is no research that precisely measures exposure to news over a period of years. This study assesses TV news consumption by analyzing respondent-level “...
