An Algorithm for the Calculation of the Pseudo-Inverse of a Singular Matrix [PDF]

The Computer Journal, 1966
An algorithm for the calculation of the pseudo-inverse of a singular matrix is derived. The method is motivated by Wiener-Kalman filtering theory and uses successive "observations" to update the "estimation" of the pseudo-inverse. Illustrative and numerical examples are given so that the speed and accuracy of the method may be compared with ordinary ...

Rethinking Charge Transport and Recombination in Donor‐Diluted Organic Solar Cells

Advanced Materials, EarlyView.
Organic solar cells with 1–45% PM6 content in Y12 were studied to link structure and charge dynamics to performance. The conductivity follows a 3D percolation model without a sharp threshold. Donor dilution preserves the photogeneration yield, but limits the fill factor due to transport resistance losses.

Control Oriented Real-Time Nonlinear Dynamic Pseudo-Inverse for Non-Minimum Phase Systems

IEEE Open Journal of Control Systems
This paper presents a novel algorithm for the dynamic inversion of nonlinear systems within the output tracking control framework, wherein the inverse serves as an open-loop nominal controller to facilitate feedback stabilization of the tracking error ...

A pseudo-inverse of a line graph

CoRR
Line graphs are an alternative representation of graphs where each vertex of the original (root) graph becomes an edge. However not all graphs have a corresponding root graph, hence the transformation from graphs to line graphs is not invertible. We investigate the case when there is a small perturbation in the space of line graphs, and try to recover ...

Switchable Magnonic Crystals Based on Spin Crossover/CrSBr Heterostructures

Advanced Materials, EarlyView.
Multiscale modeling is employed to investigate the functionality of a light‐controlled, tunable magnonic crystal based on spin‐crossover Fe‐pz molecules integrated with a monolayer of CrSBr. Ab initio simulations confirm that the molecules remain functional on the CrSBr surface, while a semiclassical elastic model demonstrates that light‐induced ...

Scalable Algorithms for Laplacian Pseudo-inverse Computation

CoRR, 2023
The pseudo-inverse of a graph Laplacian matrix, denoted as $L^\dagger$, finds extensive application in various graph analysis tasks. Notable examples include the calculation of electrical closeness centrality, determination of Kemeny's constant, and evaluation of resistance distance.

A Geometrically Transient Platform for Bioelectronic Implants

Advanced Materials, EarlyView.
Minimally invasive bioelectronic implants often compromise performance for smaller sizes. To resolve this optimization dilemma, a wireless bioelectronic implant with a transient geometry is introduced (MiFi). The origami‐inspired device miniaturizes up to sixfold for syringe insertion and autonomously unfolds post‐implantation.
