background: primary dysmenorrhea is the most common cyclic pelvic pain and is also the most common gynecological problem worldwide and affects quality of life. the present study aimed to investigate the effect of isometric exercises on intensity and duration of pain and level of anxiety in the students with primary dysmenorrhea. materials and methods : in this randomized controlled clinical tri...

Aims: Active and progressive resistance training has a key role in functional recovery and quality of life in patients with MS. Therefore, this study aimed to investigate the effects of isotonic and isometric exercises on balance and ability in patients with MS. Materials & Methods: In this randomized clinical trial, 60 patients with MS admitted to MS Special Diseases Center in Yasuj during 20...

OBJECTIVE To determine whether isometric exercise increases collateral flow in remote ischaemic myocardium in acute coronary occlusion models of patients with coronary artery disease. DESIGN A randomized controlled study. SUBJECTS Sixty-five patients with 1-vessel coronary artery disease. METHODS Subjects were randomly assigned to either the isometric exercise group or non-exercise group....

MaximumVariance Unfolding is one of the main methods for (nonlinear) dimensionality reduction. We study its large sample limit, providing specific rates of convergence under standard assumptions. We find that it is consistent when the underlying submanifold is isometric to a convex subset, and we provide some simple examples where it fails to be consistent.

We define a Riemannian metric g on a manifold M to be heterogeneous if no two distinct points of M have isometric neighborhoods. Intuitively, a heterogeneous metric is as far as possible from being homogeneous. Heterogeneity can be reformulated in terms of a multijet transversality condition so that by an application of the standard transversality theorems, the genericity of heterogeneous metri...

Let x : (M, F ) →֒ (V n+1, F ) be a simply connected hypersurface in a Minkowski space (V n+1, F ). In this paper, using the Gauss formula of Chern connection on Finsler submanifolds, we shall prove that if x(p) is normal to Tp(M)(∀p ∈ M), then M with the induced metric is isometric to the standard Euclidean sphere.

The continuous deformation of any spherical isometric folding into the standard spherical folding, , s f defined by ( ) ( ) , , , , , z y x z y x fs = remains an open problem since 1989. We show that this conjecture is restricted to the class of primitive foldings and it is exhibited a spherical folding within this class, where the difficulty of deformation is evidenced.

A uniformly p-to-one endomorphism is a measure-preserving map with entropy log p which is almost everywhere p-to-one and for which the conditional expectation of each preimage is precisely 1/p. The standard example of this is a one-sided p-shift with uniform i.i.d. Bernoulli measure. We give a characterization of those uniformly finite-to-one endomorphisms conjugate to this standard example by ...
