Lower extremity amputation not only limits mobility, but also increases the risk of knee osteoarthritis of the intact limb. Dynamic walking models of non-amputees suggest that an appropriately timed push-off from the trailing limb can reduce collision forces on the leading limb. These collision forces may determine the peak knee external adduction moment (EAM), which has been linked to the deve...
We prove PSPACE-completeness of a class of pushingblock puzzles similar to the classic Sokoban, extending several previous results [1, 5, 12]. The puzzles consist of unit square blocks on an integer lattice; some of the blocks are movable. The robot may move horizontally and vertically in order to reach a specified goal position. The puzzle variants differ in the number of blocks that the robot...
[Purpose] This study investigated the effect of push-up exercise with hip adduction on the COP deviation and SA and L1 spinal muscle activation. [Subjects] Twelve males aged 20-30 years were recruited. [Methods] We measured the COP deviation and SA and L1 spinal muscle activities during push-up exercise with and without hip adduction [Results] The COP deviation significantly decreased and the S...
A new class of languages, called multi-push-down (mpd), that generalize the classical context-free (cf, or Chomsky type 2) ones is introduced. These languages preserve some important properties of cf languages: a generalization of the Chomsky-Schh utzenberger homomorphic characterization theorem, the Parikh theorem and a \pumping lemma" are proved. Multi-push-down languages are an AFL. Their re...
Background and Aims: Slow polymerization rate in early stage of light curing process leads to higher monomers movement and entering in polymer network that cause higher mechanical properties.The aim of this study was to evaluate the effect of light activation methodes (immediate, 5 and 10 minutes delay) on the push-out bond strength of cemented fiber posts in different regions of root canal...
