Observations of the Marinov Motor

Radoslav Marinov

For some functions h (for example hz(w) = 1w≤z), the left-hand-side of (2) is a distance between a variable W and Z and we can bound that distance by taking advantage of the structures of h and W to bound the right-hand-side of (2). For example, by taking h such that the supremum of E[h(W )−Eh(Z)] yields the Wasserstein metric, and taking W = ∑ Xi/n for a sequence of independent mean-zero-varia...

Boundedness of the Riesz Projection on Spaces with Weights

Let ∂D be the unit circle in the complex plane, define the function χ on ∂D by χ(eiθ) = eiθ, and set P = {p : p = ∑Nk=−N ckχ}. Let σ be normalized Lebesgue measure on ∂D. The Riesz projection P+ is defined on P by the formula P+( ∑N k=−N ckχ k) = ∑N k=0 ckχ k. In [4], Paul Koosis proved: Theorem 1 (Koosis). Given a non-negative function w ∈ L1, there exists a non-negative, non-trivial function ...

Effects of Proprioceptive and Visual Disturbance on Inphase and Anti-phase Hand Performance

Purpose: The present study aimed to investigate the effect of sensory and movement speed manipulations on bimanual coordination dynamics. Here we compared to what extent the absence and or bias of different sensory modalities affect performance of coordination of movements. Methods: Fifteen physical education students of Shahid Beheshti University (aged 18-25 years) were partici...
