    摘要: The present disclosure is directed to a halogen-free composition and conductors coated with the halogen-free composition. The halogen-free composition includes (A) from 70 wt % to 85 wt % of a polymeric component and (B) from 30 wt % to 15 wt % of a halogen-free flame retardant. The polymeric component (A) includes (i) a propylene homopolymer or a mini-random copolymer with greater than 40% crystallinity and (ii) an ethylene/α-olefin copolymer. The halogen-free composition has a density less than 1.15 g/cc. The halogen-free composition also has a scrape abrasion resistance of greater than or equal to 350 cycles as measured in accordance with ISO 6722.

    摘要: The present disclosure relates to iterative reconstruction of images. In certain embodiments, a deconvolution filter is used to approximate the inversion of a Hessian matrix associated with the reconstruction. In one such embodiment, the desired image is not reconstructed directly in the iterative process. Instead, an image is reconstructed that yields the desired image when filtered by the deconvolution filter.

    摘要: Methods are provided for iteratively reconstructing an image signal to generate a reconstructed image signal. In one embodiment, sub-iterations of each iteration are performed on pixel or voxel subsets. The subsets may be composed of neighboring or spatially separated pixel or voxels and may extend in the z-direction. In one embodiment, an update step of the iterative reconstruction involves the direct inversion of an approximation of a Hessian matrix associated with the respective subsets. In further embodiments, non-negativity or other limitations or constraints on update values may be enforced.
