The community structure of a complex network can be determined by finding the partitioning its nodes that maximizes modularity. Many proposed algorithms for doing this work recursively bisecting network. We show unduely constrains their results, leading to bias in size communities they find and limiting effectivness. To solve problem, we propose adding step existing does not increase order computational complexity. that, if is combined with commonly used method, identified constraint...

In this paper we discuss the use of total angular momentum representation in close coupling-wave packet (CCWP-J) method for solving time dependent Schrödinger equation inelastic, nonreactive gas phase atom–diatom collisions. This enables wave propagation relative motion to be reduced from three dimensions one. The approach utilizes a coupling expansion into subpackets labeled by quantum numbers J, z-component m0, rotor j, and orbital l. number coupled is less than plane boundary condition...
The theory of Alfv\'en resonance effects on the wave modes a tokamak is extended beyond incompressible magnetohydrodynamic model to include finite-($\frac{\ensuremath{\omega}}{{\ensuremath{\Omega}}_{i}}$) and compressibility. discrete spectrum compressional waves consists sequence frequencies with finite damping decrements resulting from resonance. finite-frequency can cause almost vanish. This permits heating via high-$Q$ eigenmodes in large tokamaks.
The close coupling wave packet (CCWP) method is formulated in a body-fixed representation for atom–rigid rotor inelastic scattering. For total J>jmax the computational cost of propagating coupled channel packets body frame scales approximately as N3/2 where N number channels. large numbers channels, this will be much more efficient than space CCWP previously developed which N2 under same conditions. Timing results are reported model system 25, 64, 144, 256, and 969 calculations were...

A strong negative radial electric field is directly observed H-mode. transient suppression normalized ion saturation floating potential fluctuation levels occurs at the low to (L–H) transition, followed by recovery near (L-mode) levels. average poloidal wave number wave-number spectral width decreased, correlation between fluctuating density reduced....
It is shown that photoabsorption in a gas of ultracold atoms depends on the sign and magnitude scattering length pair atoms. Measurements fluorescence ${}^{7}$Li are interpreted to show triplet negative singlet positive.
We propose new basis sets for linear algebraic variational calculations of transition amplitudes quantum-mechanical scattering problems. These are hybrids those that yield the Kohn principle (KVP) and generalized Newton (GNVP) when substituted in Schlessinger's stationary expression T operator. Trial show efficiencies almost as great GNVP much greater than KVP can be obtained even with majority members independent energy.

The combined band oscillator strength of the δ(0,0) and β(7,0) bands nitric oxide has been measured in absorption by utilizing a vacuum ultraviolet Fourier transform spectrometer to resolve rotational line profiles. We give accurate positions bands, improved term values up J=19.5 for C 2Π(v=0) J=8.5 B 2Π(v=7) levels, from ground state. A deperturbation procedure used on mixed calculated molecular constants are good agreement with previous work.

We present a new formalism of the generalized Newton variational principle for calculation quantum mechanical state-to-state reaction probabilities. The reformulation involves solving directly transition matrix rather than reactance so that calculations may be carried out individual columns without obtaining solutions all possible initial channels. compare convergence with real and complex boundary conditions H+H2→H2+H, O+H2→OH+H, O+HD→OH+D OD+H.
