Purpose The purpose of this study is (1) to compare the photothermal effect induced by near infrared laser light among the different shapes of iron oxide nanoparticles (IONPs) loaded micelles and (2) to determine the factors contributing to thermal production of IONPs. Methods IONPs with different shapes were synthesized by using previously published method (Ho, Chem mater, 2011) with modificat...

We introduce string-bond states, a class of states obtained by placing strings of operators on a lattice, which encompasses the relevant states in quantum information. For string-bond states, expectation values of local observables can be computed efficiently using Monte Carlo sampling, making them suitable for a variational algorithm which extends the density matrix renormalization group to hi...

In this paper, the class of random irregular block-hierarchical networks is defined and algorithms for generation and calculation of network properties are described. The algorithms presented for this class of networks are more efficient than known algorithms both in computation time and memory usage and can be used to analyze topological properties of such networks. The algorithms are implemen...

Multidestination message passing has been proposed as a mechanism to achieve eecient multicast in regular direct and indirect networks. The application of this technique to parallel systems based on irregular networks has, however, not been studied. In this paper we propose two schemes for performing multicast using multidestination worms on irregular networks and examine the extent to which mu...

Networks of workstations are emerging as a costeffective alternative to parallel computers. The interconnection between workstations usually relies on switchbased networks with irregular topologies. This irregularity makes routing and deadlock avoidance quite complicated. Current proposals avoid deadlock by removing cyclic dependencies between channels and therefore, many messages are routed al...

The position of nodes is the critical foundation for information transfer between “person to things” and “things at any time from location in wireless multi-hop networks. hop-based positioning technology has received widespread attention because it does not requiring additional ranging devices. However, most existing algorithms ignore network topology irregularities issues, which are frequently...
