Impwtant aspects of mission operations for spacecraft (S/C) sent to explore outer space are: engineering subsystem performance analysis, characterization, and commanding, all involving a substantial amount of human resources and time. Recent efforts have brought about several productivity enhancement measures within the mission operations area that incluck the streamlining of the operations pro...

We construct Nielsen-Olesen vortex solution in the noncommutative abelian Higgs model. We derive the quantized topological flux of the vortex solution. We find that the flux is integral by explicit computation in the large θ limit as well as in the small θ limit. In the context of a tachyon vortex on the braneantibrane system we demonstrate that it is this topological charge that gives rise to ...

Supersymmetric left-right models are well motivated extensions of the Minimal Supersymmetric Standard Model since they automatically contain the ingredients to explain the observed neutrino masses and mixings. Here we study a SUSY model in which the leftright symmetry is broken by triplets at a high scale leading to automatic R-parity conservation at low energies. The sparticle spectra in this ...

We present final measurements of the Z boson-lepton coupling asymmetry parameters Ae, Aμ, and Aτ with the complete sample of polarized Z bosons collected by the SLD detector at the SLAC Linear Collider. From the leftright production and decay polar angle asymmetries in leptonic Z decays we measure Ae = 0.1544 ± 0.0060, Aμ = 0.142 ± 0.015, and Aτ = 0.136 ± 0.015. Combined with our left-right asy...

Crowdsourcing is an effective and powerful tool for firms to solve practical issues and develop innovative products, but the relationship between risks and performance in crowdsourcing has received insufficient attention. Based on a dataset of 163 samples from China, social subsystem risk is empirically found to negatively influence crowdsourcing performance, whereas technical subsystem risk af...

Subsystem codes protect quantum information by encoding it in a tensor factor of a subspace of the physical state space. Subsystem codes generalize all major quantum error protection schemes, and therefore are especially versatile. This paper introduces numerous constructions of subsystem codes. It is shown how one can derive subsystem codes from classical cyclic codes. Methods to trade the dim...
