TL;DR: A motion compensated frame rate up-conversion algorithm that uses the expanded range of the motion trajectory to enhance the accuracy of motion estimation and the weighted index-based bidirectional motion compensated interpolation to reduce artifacts is presented.

TL;DR: A new motion estimation algorithm for frame rate up-conversion that enhances the estimation accuracy of motion vectors by using the unidirectional and bidirectional matching ratios of blocks in the previous and current frames and uses motion vector validity to evaluate the accuracy ofmotion vectors thereby avoiding false motion vectors.

TL;DR: In this paper, the authors investigate the effect of the triple helix system and habitat on birth and death rates of U.S. firms at the state level and find that industrial R&D expenditure plays an important role in promoting regional firm birth.

TL;DR: In this paper, the authors show that transgranular hydrogen embrittlement in 5.5Ni steel is primarily an interlath cracking phenomenon and that the fracture surface generally follows martensite lath boundaries.

TL;DR: The authors examined the effect of the Fukushima disaster on public acceptance of nuclear energy in 42 countries and found that the operational experience of nuclear power generation which has significantly affected positive public opinion about nuclear energy became considerably negative after the disaster, suggesting fundamental changes in public acceptance regardless of the level of acceptance before the disaster.
