Perturbative Renormalization of Improved Lattice Operators [PDF]
, 1997 We derive bases of improved operators for all bilinear quark currents up to spin two (including the operators measuring the first moment of DIS Structure Functions), and compute their one-loop renormalization constants for arbitrary coefficients of the ...

Two-particle renormalizations in many-fermion perturbation theory: Importance of the Ward identity
, 2002 We analyze two-particle renormalizations within many-fermion perturbation expansion. We show that present diagrammatic theories suffer from lack of a direct diagrammatic control over the physical two-particle functions.

Time-dependent control of ultracold atoms and Bose-Einstein condensates in magnetic traps [PDF]
, 1997 With radiofrequency fields one can control ultracold atoms in magnetic traps. These fields couple the atomic spin states, and are used in evaporative cooling which can lead to Bose-Einstein condensation in the atom cloud.

Cracking of Martensitic Alloy EP-823 Under Controlled Potential
Journal of Materials Engineering and Performance, 2006 The susceptibility of martensitic Alloy EP-823 to stress corrosion cracking was evaluated with and without an applied cathodic potential using the slow-strain-rate (SSR) testing technique. The magnitude of the applied potential was based on the corrosion potential determined by cyclic polarization.

Advances in decoherence control
, 2004 I address the current status of dynamical decoupling techniques in terms of required control resources and feasibility. Based on recent advances in both improving the theoretical design and assessing the control performance for specific noise models, I ...

EPS Current Tracking Method Research Based on Hybrid Sensitivity H∞ Control Algorithm
Journal of Electrical and Computer Engineering, 2018 For electric power steering system (EPS), road interference, noise of the sensor, and the uncertainty of the steering system may make EPS control effect and the driver's road sense worse. EPS system which takes advantage of good current tracking ability,

Momentum state engineering and control in Bose-Einstein condensates
, 2001 We demonstrate theoretically the use of genetic learning algorithms to coherently control the dynamics of a Bose-Einstein condensate. We consider specifically the situation of a condensate in an optical lattice formed by two counterpropagating laser ...

Coherent control of a self-trapped Bose-Einstein condensate [PDF]
, 2006 We study the behavior of a Bose-Einstein condensate held in an optical lattice. We first show how a self-trapping transition can be induced in the system by either increasing the number of atoms occupying a lattice site, or by raising the interaction ...

Power system monitoring and source control of the Space Station Freedom DC power system testbed [PDF]
Unlike a terrestrial electric utility which can purchase power from a neighboring utility, the Space Station Freedom (SSF) has strictly limited energy resources; as a result, source control, system monitoring, system protection, and load management are ...
