Periodic Orbits in Periodic Discrete Dynamics
(Elsevier, 2008)
We study the combinatorial structure of periodic orbits of nonautonomous difference equations 𝒳ₙ₊₁ = 𝒇ₙ(𝒳ₙ) in a periodically fluctuating environment. We define the Ӷ-set to be the set of minimal periods that are not ...
Analysis of Sawdust by X-ray Photoelectron Spectroscopy
(American Vacuum Society, 2005)
Determining the chemical structure and composition of biomass fuels using x-ray photoelectron spectroscopy (XPS) can provide fundamental knowledge of their structures that is useful in understanding and predicting their ...
Ultrasonic release of doxorubicin from Pluronic P105 micelles stabilized with an interpenetrating network of N,N diethylacrylamide
(Elsevier, 2002)
Pluronic P105 micelles sequester hydrophobic drugs and release them upon insonation with low frequency ultrasound; however these micelles dissolve relatively quickly upon dilution. The objective of this research was to ...
Anti-bacterial self-assembled nanotubes of cyclic d, l-alpha-peptides
(AIP Publishing, 2007)
Cyclic D, L‐α‐peptides can be designed to spontaneously partition into lipid and cell membranes where they self‐assemble into membrane‐permeating nanotubes and result in disruption of membrane potentials leading to rapid ...
Hybrid DCT/Pixel Domain Architecture for Heterogeneous Video Transcoding
(Elsevier, 2003)
In this paper the pixel domain heterogeneous video transcoder proposed by the authors is implemented in the DCT domain. Consequently, the motion compensation and its inverse and the image down-sampling functions of the ...
Stabilization of Pluronic P-105 Micelles with an Interpenetrating Network of N,N-Diethylacrylamide
(American Chemical Society, 2000)
N,N-Diethylacrylamide (NNDEA) was polymerized in the presence of Pluronic P-105 micelles. The polymerizations resulted in an interpenetrating network of poly(NNDEA) and P-105 that stabilized the micelles at concentrations ...
Analysis of Shea Nut Shells by X-ray Photoelectron Spectroscopy
(American Vacuum Society, 2005)
Determining the chemical structure and composition of biomass fuels using x-ray photoelectron spectroscopy (XPS) can provide fundamental knowledge of their structures that is useful in understanding and predicting their ...
Investigating the mechanism of acoustically activated uptake of drugs from Pluronic micelles
(BioMed Central (BMC), 2002)
Background: This paper examines the mechanism of ultrasonic enhanced drug delivery from Pluronic micelles. In previous publications by our group, fluorescently labeled Pluronic was shown to penetrate HL-60 cells with and ...
Using Artificial Neural Networks and Model Predictive Control to Optimize Acoustically Assisted Doxorubicin Release from Polymeric Micelles
(SAGE Publications, 2009)
We have been developing a drug delivery system that uses Pluronic P105 micelles to sequester a chemotherapeutic drug - namely, Doxorubicin (Dox) - until it reaches the cancer site. Ultrasound is then applied to release the ...
Telescopic Vector Composition and Polar Accumulated Motion Residuals for Feature Extraction in Arabic Sign Language Recognition
(Springer, 2007)
This work introduces two novel approaches for feature extraction applied to video-based Arabic sign language recognition, namely, motion representation through motion estimation and motion representation through motion ...
