Electric and magnetic form factors of strange baryons

open access: yes, 2003
Predictions for the electromagnetic form factors of the Lambda$, Sigma and Xi hyperons are presented. The numerical calculations are performed within the framework of the fully relativistic constituent-quark model developed by the Bonn group.

Reconclining phi radiative decays with other data for a0(980), fo(980), pi-pi -> KK and pi-pi -> eta-eta

open access: yes, 2006
Data for phi -> gamma (eta-pizero) are analysed using the KK loop model and compared with parameters of a0(980) derived from Crystal Barrel data. The eta-pi mass spectrum agrees closely and the absolute normalisation lies just within errors. However, BES

Focusing on Demand Side Management in the Future of the Electric Grid [PDF]

open access: yes, 2010
The widespread blackout that occurred on August 14, 2003 (“the blackout”) exposed the weaknesses of the current electric transmission grid structure, and underscored the need for improvements to the transmission grid in the United States.

New NLO Parametrizations of the Parton Distributions in Real Photons

open access: yes, 2005
We present new NLO sets of parton distributions in real photons based on a scheme invariant definition of the non-perturbative input. We compare the theoretical predictions with LEP data and a best fit allows us to constrain the parameters of the ...

Secure direct communication using Einstein-Podolsky-Rosen pairs and teleportation

open access: yes, 2003
A novel scheme for secure direct communication between Alice and Bob is proposed, where there is no need for establishing a shared secret key. The communication is based on Einstein-Podolsky-Rosen pairs and teleportation between Alice and Bob.

Source localization in random acoustic waveguides [PDF]

open access: yes, 2010
Mode coupling due to scattering by weak random inhomogeneities in waveguides leads to loss of coherence of wave fields at long distances of propagation. This in turn leads to serious deterioration of coherent source localization methods, such as matched ...

Some consequences of a noncommutative space-time structure

open access: yes, 2004
The existence of a fundamental length (or fundamental time) has been conjecture in many contexts. Here one discusses some consequences of a fundamental constant of this type, which emerges as a consequence of deformation-stability considerations leading ...
