Matrix compensation and diagonal compensation
Journal of Computational and Applied Mathematics, 1995 AbstractMatrix compensation is introduced to preserve the positivity of matrices when we construct preconditioners for positive-definite matrices. Diagonal compensation for symmetric positive-definite matrices is generalized to positive-definite matrices.

Autocollimating compensator for controlling aspheric optical surfaces [PDF]
, 2014 A compensator (null-corrector) for testing aspheric optical surfaces is proposed, which enables i) independent verification of optical elements and assembling of the compensator itself, and ii) ascertaining the compensator position in a control layout for a specified aspheric surface.

Neural Networks Compensation of Systems with Multi-segment Piecewise Linear Nonlinearities [PDF]
arXiv, 2021 A neural networks (NN) compensator is designed for systems with multi-segment piecewise-linear nonlinearities. The compensator uses the back stepping technique with NN for inverting the multi-segment piecewise-linear nonlinearities in the feedforward path.

Airborne Levels of Lung Carcinogens at an Ascon Manufacturing Site
Aerosol and Air Quality Research, 2020 We assessed the airborne concentrations of the dust (both total and respirable), quartz, polycyclic aromatic hydrocarbons, and elemental carbon in an ascon manufacturing environment to determine the exposure to operators and the likelihood of developing ...

Distributed Stabilization of Signed Networks via Self-loop Compensation [PDF]
arXiv, 2021 This paper examines the stability and distributed stabilization of signed multi-agent networks. Here, positive semidefiniteness is not inherent for signed Laplacians, which renders the stability and consensus of this category of networks intricate.

Insights into PI3K/AKT signaling in B cell development and chronic lymphocytic leukemia
FEBS Letters, EarlyView.This Review explores how the phosphoinositide 3‐kinase and protein kinase B pathway shapes B cell development and drives chronic lymphocytic leukemia, a common blood cancer. It examines how signaling levels affect disease progression, addresses treatment challenges, and introduces novel experimental strategies to improve therapies and patient outcomes.

Taurine promotes glucagon‐like peptide‐1 secretion in enteroendocrine L cells
FEBS Letters, EarlyView.Taurine, a sulfur‐containing amino acid, is likely taken up by enteroendocrine L cells via the taurine transporter. This process increases the levels of cytosolic ATP. The increase in intracellular Ca2+ concentrations and glucagon‐like peptide‐1 secretion through membrane depolarization is caused by the closure of ATP‐sensitive potassium channels ...

FEBS Letters, EarlyView.Venom peptides have shown promise in treating pain. Our study uses computer screening to identify a peptide that targets a sodium channel (NaV1.7) linked to chronic pain. We produced the peptide in the laboratory and refined its design, advancing the search for innovative pain therapies.
