However, the IOM(q) exhibites irregular convergence behavior with wild oscillation in the residual norms though it tends to decrease in a very slow manner, which is owing to the lack of minimization property over the Krylov subspace. QMR method proposed by Freund, Gutknecht and Nachtigal, owing to its ability to avoid breakdowns and smooth convergence behavior, is a robust iterative solver for general nonsingular unsymmetric linear systems. In this paper, we propose a novel quasi-minimal residual (QMR) variant of the Incomplete Orthogona- lization Method (IOM(q)). Numerical experiments show that it has smooth convergence behavior and is more effective, especially when using its restarted version.展开更多

Methods: Caller data with identifiers removed were extracted from a cancer helpline database. Baseline data included calls made to the helpline between April 2, 2008 and September 2, 2009 (Period 1). Then, a second data set was built from data collected between September 3, 2009 and May 2, 2011 (Period 2). Results: The major reasons for calls to the cancer telephone helpline during the two different time periods were the same: financial assistance, helpline services information, coping assistance, support groups, and questions related to treatment. Four of the top five reasons were non-treatment related (i.e., financial issues, helpline services information, coping, and support). Conclusions: The nature of calls to the helpline suggests that the financial and psychosocial needs of people with cancer are not being addressed by healthcare providers. Practice implications: The new “normal” for cancer care includes decisions about complex care coupled with new regulatory and financial constraints. This underscores the importance of focused planning of cancer care across multiple care settings in order to ensure continuity of care for the whole person.展开更多

It is shown that the inverse of a general nonsingular j × j Hessenberg matrir can be updated in O(j2) flops from that of its (j -1) × (j - 1) principal submatrir. The updating recursion of inverses of the Hessenberg matrices does not need any QR or LU decompostion as commonly used in the literature. Some updating recursions of the residual norms and the approximate solutions obtained by these two methods are derived. These results are appealing because they allow one to decide when the methods converge and show one how to compute approximate solutions very cheaply and easily.展开更多
