Perturbationresilient blockiterative projection methods with application to image reconstruction from projections
, 2009
"... A blockiterative projection algorithm for solving the consistent convex feasibility problem in a finitedimensional Euclidean space that is resilient to bounded and summable perturbations (in the sense that convergence to a feasible point is retained even if such perturbations are introduced in eac ..."

Normal forms of hierarchies of integrable PDEs, Frobenius manifolds and GromovWitten invariants
, 2001
"... We present a project of classification of a certain class of bihamiltonian 1+1 PDEs depending on a small parameter. Our aim is to embed the theory of Gromov Witten invariants of all genera into the theory of integrable systems. The project is focused at describing normal forms of the PDEs and their ..."

Dbranes and deformation quantization
 JHEP
, 1999
"... In this note we explain how worldvolume geometries of Dbranes can be reconstructed within the microscopic framework where Dbranes are described through boundary conformal field theory. We extract the (noncommutative) worldvolume algebras from the operator product expansions of open string verte ..."

General Deviants: An Analysis of Perturbations in Compressed Sensing
, 2009
"... Abstract—We analyze the Basis Pursuit recovery method when observing signals with general perturbations (i.e., additive, as well as multiplicative noise). This completely perturbed model extends the previous work of Candès, Romberg and Tao on stable signal recovery from incomplete and inaccurate mea ..."

Faster imaging with randomly perturbed, undersampled spirals and l1 reconstruction
 in Proceedings of the 13th Annual Meeting of ISMRM
, 2005
"... We propose a fast imaging method based on undersampled kspace spiral sampling and nonlinear reconstruction. Our approach is inspired by theoretical results in sparse signal recovery [1,2] showing that compressible signals can be completely recovered from randomly undersampled frequency data. Since ..."

Starobinsky, Reconstructing Cosmological Matter Perturbations using Standard Candles and Rulers
"... For a large class of dark energy (DE) models, for which the effective gravitational constant is a constant and there is no direct exchange of energy between DE and dark matter (DM), knowledge of the expansion history suffices to reconstruct the growth factor of linearized density perturbations in th ..."

Secondorder reconstruction of the inflationary potential
 Physical Review D
, 1994
"... To first order in the deviation from scale invariance the inflationary potential and its first two derivatives can be expressed in terms of the spectral indices of the scalar and tensor perturbations, n and nT, and their contributions to the variance of the quadrupole CBR temperature anisotropy, S a ..."

, S and T. In addition, there is a “consistency relation ” between these quantities: nT = −1 T. We discuss the overall strategy of perturbative reconstruction and 7 S derive the secondorder expressions for the inflationary potential and its first two derivatives and the firstorder expression for its third
Reconstruction of a genetic network from gene perturbation data
 J. Kor. Phys. Soc
, 2006
"... We propose a new method for reconstructing a gene regulatory network from a gene expression profile. In this method we directly use the gene expression level as a weight of weighted network between genes. Each gene expression level is checked by means of a pvalue test for each experiment to gain th ..."

Using Perturbative Least Action to Reconstruct Redshift Space Distortions
, 2000
"... In this paper, we present a redshift space reconstruction scheme which is analogous to and extends the Perturbative Least Action (PLA) method described by Goldberg & Spergel (2000). We first show that this scheme is effective in reconstructing even nonlinear observations. We then suggest that by ..."
