Definition 1.1. [8] An oriented knotK is a topologically slice knot if there is an oriented embedded locally flat disk D2 ⊆ D4 whose boundary ∂D2 ⊂ ∂D4 = S3 is the knot K. Here locally flat means locally homeomorphic to a standardly embedded R2 ⊆ R4. Two knots K1,K2 are concordant if there is an embedded locally flat annulus S 1 × I ⊂ S3 × I such that ∂(S1×I) ⊆ S3×I is the disjoint union of the...

OBJECTIVE The Cochran-Armitage trend test based on the linear regression model has become a standard procedure for association testing in case-control studies. In contrast, the logistic regression model is generally used for estimating effect sizes. The aim of this paper is to propose an approach that allows for association testing and parameter estimation by means of the same statistic. METH...

PURPOSE sarcopenia plays a principal role in the pathogenesis of frailty and functional impairment that occur with aging. There are few published accounts that examine the overall benefit of resistance exercise (RE) for lean body mass (LBM) while considering a continuum of dosage schemes and/or age ranges. Therefore, the purpose of this meta-analysis was to determine the effects of RE on LBM in...

Likelihood ratio (LR) tests for association and for interaction are examined for three-way contingency tables, in particular, the widely used 2 2 K tables. Mutual information identities are used to characterize the information decomposition and the logical relations between the omnibus LR test for conditional independence across K strata and its two independent components, the LR tests for homo...
