Small-angle neutron scattering (SANS) is employed to investigate the structure and longchain branch (LCB) content of metallocene-catalyzed polyethylene (PE). A novel scaling approach is applied to SANS data to determine themole fraction branch content (φbr) of LCBs in PE. The approach also provides the average number of branch sites per chain (nbr) and the average number of branch sites per min...

The problem of finding multi-constrained paths has been addressed by several QoS routing algorithms. While they generally satisfy the application requirements, they often do not consider the perspective of service providers. Service providers aim at maximizing the throughput and the number of accepted requests. These goals have been addressed by traffic engineering algorithms considering bandwi...

Segniliparus rugosus represents one of two species in the genus Segniliparus, the sole genus in the family Segniliparaceae. A unique and interesting feature of this family is the presence of extremely long carbon-chain length mycolic acids bound in the cell wall. S. rugosus is also a medically important species because it is an opportunistic pathogen associated with mammalian lung disease. This...

We propose some new two-stage stopping procedures to construct absolute-width and relative-width confidence intervals for a simulation estimator of the steady-state mean of a stochastic process. The procedures are based on the method of standardized time series proposed by Schruben and on Stein’s two-stage sampling scheme. We prove that our two-stage procedures give rise to asymptotically valid...
