Synthesis of iron oxide nanoparticles in a polyimide matrix

Journal of Colloid and Interface Science, 2004
A monolayer of gamma-Fe(2)O(3) nanoparticles embedded in a polyimide (PI) matrix was fabricated by oxidizing an Fe metal film between two PI precursor layers. There was a critical Fe thickness ( approximately 7 nm) above which a continuous layer of gamma-Fe(2)O(3) film was formed in the PI film.

Regulation of extracellular matrix synthesis by mechanical stress

Biochemistry and Cell Biology, 1996
The extracellular matrix (ECM) provides mechanical support to tissues and is a substrate for cell adhesion and differentiation. Cells bind to ECM via specific cell surface receptors such as integrins. When engaging with ECM ligands, these receptors can activate signal tranduction pathways within the cells and may act as mechanochemical transducers ...

Superior synthesis using Boolean matrix computation

[1993] Proceedings IEEE International Conference on Robotics and Automation, 2002
Discrete-event systems are modeled by finite state machines using Boolean matrices and vectors. A supervisor synthesis method for such discrete event systems using Boolean matrix computations is proposed. The supervisor synthesis algorithm is practical to implement, since the size of the Boolean state vector in the product system does not increase ...

Analysis and Synthesis of Digital Structure by Matrix Method

2007
This paper presents a general matrix algorithm for analysis and synthesis of digital filters. A useful method for computing the state-space matrix of a general digital network and a new technique for the design of digital filters are shown by means of examples.

Effects of Nanomaterials on Synthesis and Degradation of the Extracellular Matrix

ACS Nano
Extracellular matrix (ECM) remodeling is accompanied by the continuous synthesis and degradation of the ECM components. This dynamic process plays an important role in guiding cell adhesion, migration, proliferation, and differentiation, as well as in tissue development, body repair, and maintenance of homeostasis.

SYNTHESIS OF CONTROLLED SOURCES BY ADMITTANCE MATRIX EXPANSION

Journal of Circuits, Systems and Computers, 2010
The admittance matrix expansion method based on using nullors and pathological mirror elements is used to provide a systematic synthesis method of controlled sources. Four new realizations of the current controlled voltage source (CCVS) using a single grounded resistor are given.

A General Matrix Factorization Method for Network Synthesis

IRE Transactions on Circuit Theory, 1955
THIS PAPER considers a new matrix factorization method for the synthesis of RLC two terminal-pair-networks. Equivalent matrices suitable for the synthesis of RLC ladder and parallel ladder networks are developed by linear transformations of matrix multiplication.
