Cell-derived microparticles and the lung

open access: yesEuropean Respiratory Review, 2016
Cell-derived microparticles are small (0.1–1 μm) vesicles shed by most eukaryotic cells upon activation or during apoptosis. Microparticles carry on their surface, and enclose within their cytoplasm, molecules derived from the parental cell, including ...

Analysis of watermarking techniques in multimedia communications [PDF]

open access: yesSerbian Journal of Electrical Engineering, 2021
Multimedia information is critical of examining, information perceived and which are illustrated by the human cerebrum. In our brain, 33% of the cortical area concentrates only on visual information processing. Digital watermarking technology is

Empirical Evaluation of Four Tensor Decomposition Algorithms [PDF]

open access: yes, 2007
Higher-order tensor decompositions are analogous to the familiar Singular Value Decomposition (SVD), but they transcend the limitations of matrices (second-order tensors).

Cerebral small vessel disease burden is associated with poststroke depressive symptoms: A 15-month prospective study [PDF]

open access: yes, 2018
Objective: All types of cerebral small vessel disease (SVD) markers including lacune, white matter hyperintensities (WMH), cerebral microbleeds, and perivascular spaces were found to be associated with poststroke depressive symptoms (PDS).

Very Large-Scale Singular Value Decomposition Using Tensor Train Networks [PDF]

open access: yes, 2014
We propose new algorithms for singular value decomposition (SVD) of very large-scale matrices based on a low-rank tensor approximation technique called the tensor train (TT) format. The proposed algorithms can compute several dominant singular values and

Path Following by SVD [PDF]

open access: yes, 2006
In this paper, we propose a path-following method for computing a curve of equilibria of a dynamical system, based upon the smooth Singular Value Decomposition (SVD) of the Jacobian matrix. Our method is capable of detecting fold points, and continuing past folds.

The covariability of sea surface temperature and MAM rainfall on East Africa using singular value decomposition analysis [PDF]

open access: yesGeographica Pannonica, 2020
The study assesses the covariability of Sea Surface Temperature (SST) and March to May (MAM) rainfall variability on East Africa (EA) from 1981 to 2018. Singular Value Decomposition (SVD) analysis reveals the significant influence of SST anomalies on MAM
