BACKGROUND Recent observational studies have shown that patients with chronic kidney disease (CKD) have higher risk of atrial fibrillation (AF) recurrence and, therefore, the value of catheter ablation therapy in patients with CKD has been doubted. The purpose of this meta-analysis was to systematically analyze the effect of CKD on recurrence of AF following catheter ablation. METHODS PubMed ...

China Abstract An alternative error bound for linear complementarity problems for BS-matrices is presented. It is shown by numerical examples that the new bound is better than that provided by García-Esnaola and Peña (Appl. Math. Lett. 25(10):1379–1383, 2012) i...

Here we prove a probabilistic contraction mapping principle in Menger spaces. This is in line with research in fixed point theory using control functions which was initiated by Khan et al. [Bull. Austral. Math. Soc., 30(1984), 1-9] in metric spaces and extended by Choudhury et al. [Acta Mathematica Sinica, 24(8) (2008), 1379-1386] in probabilistic metric spaces. An example has also been constru...

This paper is concerned with mixed monotone mappings in partially ordered cone metric spaces. We establish several fixed point theorems, which generalize and complement some known results. Especially, even in a partially ordered metric space, our main results are generalizations of the fixed point theorems due to Bhaskar and Lakshmikantham [T. Grana Bhaskar, V. Lakshmikantham, Fixed point theor...
