Operator approach to analytical evaluation of Feynman diagrams
, 2007 The operator approach to analytical evaluation of multi-loop Feynman diagrams is proposed. We show that the known analytical methods of evaluation of massless Feynman integrals, such as the integration by parts method and the method of "uniqueness ...

Evolution-Operator-Based Single-Step Method for Image Processing
International Journal of Biomedical Imaging, 2006 This work proposes an evolution-operator-based single-time-step method for image and signal processing. The key component of the proposed method is a local spectral evolution kernel (LSEK) that analytically integrates a class of evolution partial ...

A New Operator and Method for Solving Interval Linear Equations
, 2013 We deal with interval linear systems of equations. We present a new operator, which generalizes the interval Gauss-Seidel method. Also, based on the new operator and properties of the well-known methods, we propose a new algorithm, called the magnitude ...

Tensor correlations in the Unitary Correlation Operator Method
, 2002 We present a unitary correlation operator that explicitly induces into shell model type many-body states short ranged two-body correlations caused by the strong repulsive core and the pronounced tensor part of the nucleon-nucleon interaction ...

Proximal Methods for Cohypomonotone Operators [PDF]
SIAM Journal on Control and Optimization, 2004 The paper under review is a valuable contribution to nonlinear functional analysis and, in particular, algorithms for finding a zero of one (or several) operator(s) \(A\) in a Hilbert space. While the first approach is given by step-wise matrix multiplication with the inverse operator of \(\text{Id} + A\), more refined versions are presented by the ...

Operant methods for mouse psychoacoustics [PDF]
Behavior Research Methods, 2006 Tone detection thresholds for a 10-kHz tone in NMRI mice were determined in psychoacoustic experiments using both a constant-stimuli procedure and a two-down/one-up adaptive-tracking procedure in the same subjects and applying identical threshold criteria (70.7% response probability).

Bregman Three-Operator Splitting Methods
Journal of Optimization Theory and Applications, 2022 AbstractThe paper presents primal–dual proximal splitting methods for convex optimization, in which generalized Bregman distances are used to define the primal and dual proximal update steps. The methods extend the primal and dual Condat–Vũ algorithms and the primal–dual three-operator (PD3O) algorithm.
