R-matrix Analysis of CNO Cycle Reactions
A multi-channel R-matrix code has been developed and used to analyse two key reactions in the CNO cycle. The N(p,γ)O reaction determines the rate of operation of the CN cycle and is critical in determining the age of globular clusters, which give estimates for the age of the universe. The low energy S-factors determined are in good agreement with recent estimates. A preliminary analysis of the ...
متن کاملGlobal R-linear GMRES for solving a class of R-linear matrix equations
We present a new minimal residual method, called global R-linear GMRES, to solve the R-linear matrix equations X + AXB = C and X + AXB = C, where C, X ∈ Cm×n, X denotes the complex conjugate of X, X its complex conjugate transpose, and A, B are complex matrices with appropriate dimensions. We show that the new method requires fewer matrix-matrix products than the global GMRES method applied to ...
متن کاملAnalysis of Nuclear Data using the R-Matrix Code SAMMY
An overview is presented of the analysis code SAMMY, used for evaluation and analysis of time-of-flight cross section data in the resolved and unresolved resonance regions. Included are brief descriptions of the methods used for generating the theoretical cross sections (R-Matrix theory), for simulating the effect of experimental conditions (such as Dopplerand resolution-broadening, multiplesca...
متن کاملConvergence analysis of the global FOM and GMRES methods for solving matrix equations $AXB=C$ with SPD coefficients
In this paper, we study convergence behavior of the global FOM (Gl-FOM) and global GMRES (Gl-GMRES) methods for solving the matrix equation $AXB=C$ where $A$ and $B$ are symmetric positive definite (SPD). We present some new theoretical results of these methods such as computable exact expressions and upper bounds for the norm of the error and residual. In particular, the obtained upper...
متن کاملGlobal Sensitivity Analysis of Biochemical Reaction Networks Via Semidefinite Programming
We study the problem of computing outer bounds for the region of steady states of biochemical reaction networks modelled by ordinary differential equations, with respect to parameters that are allowed to vary within a predefined region. Using a relaxed version of the corresponding feasibility problem and its Lagrangian dual, we show how to compute certificates for regions in state space not con...
