Interpreting IDR as a Petrov--Galerkin Method
The IDR method of Sonneveld and van Gijzen [SIAM J. Sci. Comput., 31:1035–1062, 2008] is shown to be a Petrov-Galerkin (projection) method with a particular choice of left Krylov subspaces; these left subspaces are rational Krylov spaces. Consequently, other methods, such as BiCGStab and ML(s)BiCGStab, which are mathematically equivalent to some versions of IDR, can also be interpreted as Petro...
متن کاملInterpreting Multiple Correspondence Analysis as a Multidimensional Scaling Method
We formulate multiple correspondence analysis (MCA) as a nonlinear multivariate analysis method that integrates ideas from multidimensional scaling. MCA is introduced as a graphical technique that minimizes distances between connecting points in a graph plot. We use this geometrical approach to show how questions posed of categorical marketing research data may be answered with MCA in terms of ...
متن کاملThe innate defense regulator peptides IDR-HH2, IDR-1002, and IDR-1018 modulate human neutrophil functions.
Although HDPs were originally hypothesized to act as antimicrobial agents, they also have been shown to broadly modulate the immune response through the activation of different cell types. We recently developed a series of novel, synthetic peptides, termed IDRs, which are conceptually based on a natural HDP, bovine bactenecin. We showed that IDR-1 and IDR-1002 protect the host against bacterial...

R eading Latino/a children’s literature has become a great passion and an important component of my work as an educator. The journey began while looking for children’s literary texts that somehow speak about aspects of my Puerto Rican/Latina identity and those communities close to mine. I was looking for personal and literary growth but also for ways in which I could share a different literary ...
