We study the numerical evaluation of Legendre polynomials $P_n$ onthe interval $[-1,1]$ via a three-term recurrence. prove that ina neighborhood an endpoint, computed approximation exactlyagrees with line tangent to at this endpoint. As aconsequence, we obtain sharp error bounds for

BACKGROUND AND PURPOSE The association between hypertension (HTN) and stroke recurrence is unclear, but may be influenced by different subtypes of stroke. This study aims to explore whether HTN contributes to the recurrence of certain subtypes of ischemic stroke (IS). METHODS Data from the China National Stroke Registry was examined and 1-year follow-up data for stroke recurrence was analyzed...

Recurrence interval of large earthquake on an active fault zone is an important parameter in assessing seismic hazard. The 2008 Wenchuan earthquake (Mw 7.9) occurred on the central Longmen Shan fault zone and ruptured the Yingxiu-Beichuan fault (YBF) and the Guanxian-Jiangyou fault (GJF). However, there is a considerable discrepancy among recurrence intervals of large earthquake in preseismic a...

BACKGROUND According to 3 randomized trials, the levonorgestrel-releasing intrauterine system significantly reduced recurrent endometriosis-related pelvic pain at postoperative year 1. Only a few studies have evaluated the long-term effectiveness of the device for preventing endometrioma recurrence, and the effects of a levonorgestrel-releasing intrauterine system as a maintenance therapy remai...
