Published: April 2015

We examine the calculation of the second and fourth moments and shifted moments of the Riemann zeta-function on the critical line using long Dirichlet polynomials and divisor correlations. Previously, this approach has proved unsuccessful in computing moments beyond the eighth, even heuristically. A careful analysis of the second and fourth moments illustrates the nature of the problem and enables us to identify the terms that are missed in the standard application of these methods.

Background: The Weight-adjusted-waist index (WWI) has emerged as a predictive factor for a range of metabolic disorders. To date, the predictive value of the WWI in relation to sarcopenia in individuals with diabetics has not been extensively explored. This study aims to investigate the impact of the WWI on the prevalence of sarcopenia among patients with type 2 diabetes mellitus (T2DM).

Objective: High D-dimer levels may increase the likelihood of unfavorable clinical outcomes in patients with acute ischemic stroke. However, the impacts of serum D-dimer levels on outcomes of reperfusion treatment in patients with acute ischemic stroke have not been evaluated. This study aims to assess a possible relationship between serum D-dimer and functional outcomes in stroke patients with endovascular treatment (EVT).
