在数值科学和应用科学中,人们经常需要考虑多种类型的序列:标量、向量、四元数、矩阵以及后来出现的张量.这些序列可能收敛,也可能发散.当它们收敛时,其收敛速度可能会非常缓慢,以至于其实际用途十分有限.在某些情况下,可以修改建立这些序列的过程,但在其他情况下,这个过程是一个无法进入的黑箱.那么,规避这一困难的一个可行方法就是将序列变换成另一个序列,希望它能收敛到相同的极限,并且收敛得更快.这种序列变换背后的思想就是外推法.本文是关于这些方法中最重要的方法以及其理论基础和算法方面的导引.本文还介绍了一些应用.

Rituximab has provided a revolutionary contribution to the treatment of B-cell non-Hodgkin’s lymphomas (NHL). A high prevalence of hepatitis C virus (HCV) infection has been described in B-cell NHL patients. Cases of liver dysfunction in HCV-positive patients have been reported with Rituximab-containing regimens. In this paper we review the recent data regarding the effects of Rituximab in NHL patients with HCV infection. We also added a section devoted to improving communication between oncohaematologists and hepatologists. Furthermore, we propose a common methodological ground to study hepatic toxicity emerging during chemotherapy.
