Locked and Unlocked Polygonal Chains in 3D
T. Biedl, E. Demaine, M. Demaine +8
In this paper, we study movements of simple polygonal chains in 3D. We say that an open, simple polygonal chain can be straightened if it can be continuously reconfigured to a stra…

Open problems from the 15th Annual ACM Symposium on Computational Geometry.
Polygonal Chains Cannot Lock in 4D
Roxana Cocan, Joseph O'Rourke
We prove that, in all dimensions d>=4, every simple open polygonal chain and every tree may be straightened, and every simple closed polygonal chain may be convexified. These recon…
Measurement of the Deuteron Spin Structure Function g_1^d(x) for 1 (GeV/c)^2 < Q^2 < 40 (GeV/c)^2
E155 Collaboration
New measurements are reported on the deuteron spin structure function g_1^d. These results were obtained from deep inelastic scattering of 48.3 GeV electrons on polarized deuterons…
Inclusive Hadron Photoproduction from Longitudinally Polarized Protons and Deuterons
The E155 Collaboration, P. L. Anthony et al
We report measurements of the asymmetry A_parallel for inclusive hadron production on longitudinally polarized proton and deuteron targets by circularly polarized photons. The phot…
