Limit properties for ratios of order statistics from exponentials

In this paper, we study the limit properties of the ratio for order statistics based on samples from an exponential distribution and obtain the expression of the density functions, the existence of the moments, the strong law of large numbers for R n i j with 1 ≤ i < j < m n = m . We also discuss other limit theorems such as the central limit theorem, the law of iterated logarithm, ...

Plasma MicroRNAs as Potential Noninvasive Biomarkers for In-Stent Restenosis

Objective To investigate whether microRNAs (miRs) can serve as novel biomarkers for in-stent restenosis (ISR). Methods This retrospective, observational single-centre study was conducted at the cardiovascular department of a tertiary hospital centre in the north of China. Follow-up coronary angiography at 6 to 12 months was performed in 181 consecutive patients implanted with ...
