Incomplete LU Preconditioner Based on Max-Plus Approximation of LU Factorization
We present a new method for the a priori approximation of the orders of magnitude of the entries in the LU factors of a complex or real matrix A. This approximation is used to determine the positions of the largest entries in...

Dec 18, 2018
BACKGROUND: 6-[Bis(carboxymethyl)amino]-1,4-bis(carboxymethyl)-6-methyl-1,4-diazepane (AAZTA ) is a promising chelator with potential advantages over 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid (DOTA) for...
Advanced functional chitosan-based nanocomposite materials for performance-demanding applications
Chitosan holds great promise for demanding applications such as functional packing and biomedical uses. There has been a notable increase in interest in combining chitosan or its derivatives with other polymers and nanofillers...
Biofunctional chitosan–biopolymer composites for biomedical applications
In light of escalating biomedical demands across diverse diseases, there arises a pressing need for the development of sophisticated biocompatible materials exhibiting augmented biological functionality. Chitosan, a cationic...
Polysaccharide–dextrin thickened fluids for individuals with dysphagia
The global aging population has brought about a pressing health concern: dysphagia. To effectively address this issue, we must develop specialized diets, such as thickened fluids made with polysaccharide–dextrin (e.g., water...

The Intergovernmental Science-Policy Platform for Biodiversity and Ecosystem Services or the Framing of Scientific Knowledge within the Law of Sustainable Development
LU Duvic-Paoli
Feb 08, 2017
The article analyses the Intergovernmental Science-Policy Platform for Biodiversity and Ecosystem Services (IPBES) through the spectrum of international environmental law. It unpacks the epistemic logics within which IPBES...
Air-Fuel Ratio Control of Spark Ignition Engines With Unknown System Dynamics Estimator
Jing Na, Anthony Siming Chen, Yingbo Huang, Ashwini Aggarwal, Andrew Lewis, Guido Hermann, Richard Burke, Chris Brace
Mar 31, 2021
This brief addresses the emission reduction of spark ignition engines by proposing a new control to regulate the air-fuel ratio (AFR) around the ideal value. After revisiting the engine dynamics, the AFR regulation is...
“Small, yet Beautiful”
We reconsider whether a grand multi-winner contest elicits more equilibrium effort than a collection of sub-contests. Fu and Lu (2009) employ a sequential winner-selection mechanism and find support for running a grand contest....
Experimental Evaluation of Conductive Flow Imaging Using Magnetic Induction Tomography
Multi-phase flow imaging is a challenging topic in industrial process tomography. In this paper, we present a non-invasive imaging technique for the electrically conductive phase of a multi-phase flow problem. Magnetic induction...
