The ability to create random models of real networks is useful for understanding the interactions in these systems. Several researchers have proposed modeling complex networks by using the node degree distribution, the most popular being a power-law distribution. Recent work by Li et al. introduced the S metric as a metric to characterize the structure of networks with power-law distributions. ...

We report the determination of high-accuracy radial velocities for 299 members of the globular cluster M92 using the Hydra multi-object spectrograph on the WIYN telescope. We have concentrated on stars outside of the central region of the cluster, located up to 14. ′ 4 from the cluster center. Candidate members were selected for spectroscopy based on a photometric metallicity index determined f...

Acoustic Doppler Current Profilers (ADCP’s) are easier to apply and more rapidly collect velocity data than traditional current-meter instruments. However, flow discharge estimates in natural rivers and canals based on ADCP measurements rely on extrapolations of the measured velocity profiles into the unmeasured zones of the flow. Furthermore, the accuracy and reliability of ADCP’s have not bee...

Given any data points xx,...,x„ in R5 and values f(xx),... ,/(x„) of a function /, Shepard's global interpolation formula reads as follows: s°pf(x) = !/(*,>,(*). "*(*) -I* *,|"7D* xj\", ' j where | ■ | denotes the Euclidean norm in R*. This interpolation scheme is stable, but if p > 1, the gradient of the interpolating function vanishes in all data points. The interpolation operator Sjj is defi...

The scaling of the bond-bond correlation function P1(s) along linear polymer chains is investigated with respect to the curvilinear distance s along the flexible chain and the monomer density rho via Monte Carlo and molecular dynamics simulations. Surprisingly, the correlations in dense three-dimensional solutions are found to decay with a power law P1(s) approximately s(-omega) with omega=3/2 ...

Several types of extra-galactic high-energy transients have been discovered, which include high-luminosity and low-luminosity long-duration gamma-ray bursts (GRBs), short-duration GRBs, supernova shock breakouts (SBOs), and tidal disruption events (TDEs) without or with an associated relativistic jet. In this paper, we apply a unified method to systematically study the redshift-dependent event ...

Grid impedance estimation is used in many power system applications such as grid connected renewable energy systems and power quality analysis of smart grids. The grid impedance estimation techniques based on signal injection uses Ohm’s law for the estimation. In these methods, one or several signal(s) is (are) injected to Point of Common Coupling (PCC). Then the current through and voltage of ...

In this paper, we develop methods for inferring tumor growth rates from the observation of tumor volumes at two time points. We fit power law, exponential, Gompertz, and Spratt’s generalized logistic model to five data sets. Though the data sets are small and there are biases due to the way the samples were ascertained, there is a clear sign of exponential growth for the breast and liver cancer...
