Adaptive non-uniform mutation based on statistics for genetic algorithms [PDF]
Copyright @ 2002 ACMAs a meta-heuristic search algorithm based on mechanisms abstracted from population genetics, the genetic algorithm (GA) implicitly maintains the statistics about the search space through the population.

Exact Superpotentials for Theories with Flavors via a Matrix Integral
We extend and test the method of Dijkgraaf and Vafa for computing the superpotential of N=1 theories to include flavors in the fundamental representation of the gauge group.

ABSTRACT This cross‐sectional study investigated the relationship between the presence and impact of ACEs with both reactive and proactive aggression, and the possible moderating role of mentalization (operationalized as reflective functioning) in these expected relationships.

The Demand for Current Public Expenditure in Fiji: Theory and Empirical Results [PDF]
The purpose of this paper is to analyse government expenditure in Iran using annual time series data for the period 1963-2000. Various theories of the size of government are reviewed and a distinction is made between economic/structural determinants and ...

Thermodynamics of viscous dark energy in an RSII braneworld
We show that for an RSII braneworld filled with interacting viscous dark energy and dark matter, one can always rewrite the Friedmann equation in the form of the first law of thermodynamics, $dE=T_hdS_h+WdV$, at apparent horizon.

Parametrization of nuclear parton distributions
Optimum nuclear parton distributions are obtained by analyzing available experimental data on electron and muon deep inelastic scattering (DIS). The distributions are given at Q^2=1 GeV^2 with a number of parameters, which are determined by a chi^2 ...

Reaction of selected winter wheat varieties to autumnal infection with Wheat dwarf virus
The response of 25 registered winter wheat varieties to autumnal infection with Wheat dwarf virus (WDV) was studied in small plot trials in two years. The materials were infected by vectors, leafhopper Psammotettix alienus Dahlbom, 1851 from three-leaf ...

Quantum symmetries of the twisted tensor products of C*-algebras
We consider the construction of twisted tensor products in the category of C*-algebras equipped with orthogonal filtrations and under certain assumptions on the form of the twist compute the corresponding quantum symmetry group, which turns out to be the
