The PZ method for estimating determinant ratios, with applications
نویسندگان
چکیده
We introduce a new method for estimating determinants or determinant ratios of large matrices, which combines the techniques of Padè approximation with rational functions and Z2 noise estimation of traces of large matrices. The method requires simultaneously solving several matrix equations, which can be conveniently accomplished using the MR method. We include some preliinary results, and indicate potential applications to non-Hermitian matrices, and Hybrid Monte Carlo without pseudofermions.

In vitro and in vivo fitness of respiratory syncytial virus monoclonal antibody escape mutants.
Respiratory syncytial virus (RSV) is the only infectious disease for which a monoclonal antibody (MAb) is used in humans. Palivizumab (PZ) is a humanized murine MAb to the F protein of RSV. PZ-resistant viruses appear after in vitro and in vivo growth of RSV in the presence of PZ. Fitness for replication could be a determinant of the likelihood of dissemination of resistant viruses. We assessed...
متن کاملPadé - Z2 Estimator of Determinants
We introduce the Padé–Z2 (PZ) stochastic estimator for calculating determinants and determinant ratios. The estimator is applied to the calculation of fermion determinants from the two ends of the Hybrid Monte Carlo trajectories with pseudofermions. Our results on the 83 × 12 lattice with Wilson action show that the statistical errors from the stochastic estimator can be reduced by more than an...
متن کاملEstimating the Optimal Dosage of Sodium Valproate in Idiopathic Generalized Epilepsy with Adaptive Neuro-Fuzzy Inference System
Introduction: Epilepsy is a clinical syndrome in which seizures have a tendency to recur. Sodium valproate is the most effective drug in the treatment of all types of generalized seizures. Finding the optimal dosage (the lowest effective dose) of sodium valproate is a real challenge to all neurologists. In this study, a new approach based on Adaptive Neuro-Fuzzy Inference System (ANFIS) was pre...

Background and Objective: Meditation is commonly perceived as an alternative medicine management tool for psychological diseases such as depression and anxiety disorders. To our knowledge, there is no published study providing an index for estimating meditation's depth from biological signals. Estimating the depth of meditation can be useful in controlling its different levels, and it can be us...
متن کاملEffect of the Synthesis Parameters on the Properties of Biphasic Ca(OH) -HA Nanopowders for Tissue Engineering Applications
Nanocrystalline hydroxyapatite was precipitated from calcium hydroxide and phosphoric acid. Effects of precipitation temperature and different calcium to phosphate ratios (Ca/P) on the obtained powders were investigated. Characteriza-tion of the powders was performed using XRD and FTIR spectra, scanning electron microscopy, and transmission electron microscopy. Increase in precipitation t...
