We suppose that S is a smooth hypersurface in Rn+1 with Gaussian curvature re and surface measure dS, it) is a compactly supported cut-off function, and we let pa be the surface measure with dßa = u>Ka dS. In this paper we consider the case where S is the graph of a suitably convex function, homogeneous of degree d, and estimate the Fourier transform ßa. We also show that if S is convex, with n...

The study investigated differences in skeletal muscle function between obese and non-obese children using a force platform. Forty obese children and adolescents (age range 8 to 18 years; 21 girls) and 40 age- and sex-matched controls performed two tests: (1) single two-legged jump, a countermovement jump for maximal height; (2) multiple one-legged hopping on the forefoot, a test of maximal forc...

Given an approach region Γ ∈ Z+ and a pair U , V of commuting nonperiodic measure preserving transformations on a probability space (Ω,Σ, μ), it is shown that either the associated multiparameter ergodic averages of any function in L(Ω) converge a.e. or that, given a positive increasing function φ on [0,∞) that is o(log x) as x → ∞, there exists a function g ∈ Lφ(L) (Ω) whose associated multipa...

A variety of results regarding multilinear Calderón-Zygmund singular integral operators is systematically presented. Several tools and techniques for the study of such operators are discussed. These include new multilinear endpoint weak type estimates, multilinear interpolation, appropriate discrete decompositions, a multilinear version of Schur’s test, and a multilinear version of the T1 Theor...

This is the third part of a series of four articles on weighted norm inequalities, off-diagonal estimates and elliptic operators. For L in some class of elliptic operators, we study weighted norm L inequalities for singular “non-integral” operators arising from L ; those are the operators φ(L) for bounded holomorphic functions φ, the Riesz transforms ∇L−1/2 (or (−∆)1/2L−1/2) and its inverse L1/...

Normalizers and p-normalizers of maximal tori in p-compact groups can be characterized by the Euler characteristic of the associated homogeneous spaces. Applied to centralizers of elementary abelian p-groups these criteria show that the normalizer of a maximal torus of the centralizer is given by the centralizer of a preferred homomorphism to the normalizer of the maximal torus; i.e. that “norm...

OBJECTIVES To determine the immediate effects of applied forearm Kinesio taping on maximal grip strength and force sense of healthy collegiate athletes. DESIGN Single group, repeated measures study. SETTING Clinical sports medicine laboratory at a university hospital. PARTICIPANTS Twenty-one healthy collegiate athletes voluntarily participated in this study. All subjects were male (averag...

t has often been demonstrated that greater improvements in key performance factors (anaerobic capacity, maximal aerobic power [MAP] and aerobic endurance) in most of the so called ‘aerobic’ sports such as cross country, middle and long distance running can be achieved through training programmes that include intermittent sessions. In fact, as shown in Table 1, when doing continuous exercise, on...

BACKGROUND Current literature suggests that novices reach a plateau after two to seven trials when training on the MIST VR laparoscopic virtual reality system. We hypothesize that significant benefit may be gained through additional training. MATERIALS AND METHODS Second-year medical students (n = 12) voluntarily enrolled under an IRB-approved protocol for MIST VR training. All subjects compl...

In this paper we derive maximal pointwise Hölder estimates for the Kohn’s Laplacian on strongly pseudoconvex CR manifolds of class C3 using the Tanaka-Webster Pseudohermitian metric. The estimates can be used to improve the Boutet De Monvel’s embedding theorem for strongly pseudoconvex compact CR manifolds of real dimension greater or equal to five with less smoothness assumption.
