Effects of postmortem interval on myelin integrity in rhesus macaque brain tissue
Brain Pathology, EarlyView.In rhesus macaque brain, progressive myelin degradation over 72 h postmortem—with increasing numbers of myelin defects—altered myelin's optical properties, increasing scattering coefficient and decreasing relative retardance, as measured by quantitative birefringence microscopy and polarization‐sensitive optical coherence tomography.

AIP Advances, 2017 In this letter, we propose a simple and efficient framework of dynamic mode decomposition (DMD) and mode selection for large datasets. The proposed framework explicitly introduces a preconditioning step using an incremental proper orthogonal ...

Energy and Entropy in Turbulence Decompositions
Entropy, 2019 The role of energy and entropy in the decomposition of turbulent velocity flow-fields is shown in this paper. Decomposition methods based on the energy concept are taken into account—proper orthogonal decomposition (POD) and its extension bi ...

Multifidelity Proper Orthogonal Decomposition
This paper introduces a multifidelity formulation that reduces the computational cost of the proper orthogonal decomposition (POD) of a high-fidelity model by leveraging data from cheaper, lower-fidelity models. POD is a prevalent technique for extracting a low-dimensional basis from training data to achieve subsequent dimension reduction or reduced ...

3D Character Reconstruction from Hand‐drawn Model Sheets
Computer Graphics Forum, EarlyView.Abstract Hand‐drawn model sheets are widely used in character design to define 3D shape and appearance through sparse multi‐view drawings. Reconstructing 3D characters from such sparse inputs has traditionally been challenging due to insufficient visual information.

On the Application of Proper Orthogonal Decomposition (POD) for In-Cylinder Flow Analysis
Energies, 2018 Proper orthogonal decomposition (POD) is a coherent structure identification technique based on either measured or computed data sets. Recently, POD has been adopted for the analysis of the in-cylinder flows inside internal combustion engines.

2D Piecewise Linear Scalar Fields with Invertible Integral Lines
Computer Graphics Forum, EarlyView.Abstract Integral lines of the gradient flow are standard features in continuously differentiable scalar fields that enjoy some useful properties: They cover the domain densely, do not split, merge, or intersect, and are therefore invertible. For widely used discretizations of scalar fields, the corresponding polygonal approximations of integral lines ...

Double Proper Orthogonal decomposition for representing and simulating turbulence fields
, 2005 The modeling and simulation of the wind field along structures is a fundamental step in the analysis of their wind-excited response. The proper orthogonal decomposition POD provides efficient tools to formulate a model of the turbulence field based on ...
