Surfactant spreading on thin viscous films: film thickness evolution and periodic wall stretch
(Springer-Verlag, 2003-01)
Surfactant spreading on thin viscous films is of interest in the context of surfactant and liquid transport in the lungs, for both normal lung function and treatment of disease, as well as for many industrial processes. ...
Fast wave propagation in auditory cortex of an awake cat using a chronic microelectrode arrayThe work was performed at Department of Bioengineering, Arizona State University, ECG 334 MS-9709 Arizona State University, Tempe, AZ 85287-9709, USA.
(IOP Publishing Ltd, 2007-06-01)
We investigated fast wave propagation in auditory cortex of an alert cat using a chronically implanted microelectrode array. A custom, real-time imaging template exhibited wave dynamics within the 33-microwire array (3 ...
TOPICAL REVIEW: Microfluidics for flow cytometric analysis of cells and particles
(IOP Publishing Ltd, 2005-06-01)
This review describes recent developments in microfabricated flow cytometers and related microfluidic devices that can detect, analyze, and sort cells or particles. The high-speed analytical capabilities of flow cytometry ...
Pragmatic fully 3D image reconstruction for the MiCES mouse imaging PET scanner
(IOP Publishing Ltd, 2004-10-07)
We present a pragmatic approach to image reconstruction for data from the micro crystal elements system (MiCES) fully 3D mouse imaging positron emission tomography (PET) scanner under construction at the University of ...
Regularized reconstruction in quantitative SPECT using CT side information from hybrid imaging
(2010-05)
A penalized-likelihood (PL) SPECT reconstruction method using a modified regularizer that accounts for anatomical boundary side information was implemented to achieve accurate estimates of both the total target activity ...
Cortical microstimulation in auditory cortex of rat elicits best-frequency dependent behaviors
(IOP Publishing Ltd, 2005-06-01)
Electrical activation of the auditory cortex has been shown to elicit an auditory sensation; however, the perceptual effects of auditory cortical microstimulation delivered through penetrating microelectrodes have not been ...
Complex impedance spectroscopy for monitoring tissue responses to inserted neural implants
(IOP Publishing Ltd, 2007-12-01)
A series of animal experiments was conducted to characterize changes in the complex impedance of chronically implanted electrodes in neural tissue. Consistent trends in impedance changes were observed across all animals, ...
A finite-element model of the mechanical effects of implantable microelectrodes in the cerebral cortex
(IOP Publishing Ltd, 2005-12-01)
The viability of chronic neural microelectrodes for electrophysiological recording and stimulation depends on several factors, including the encapsulation of the implant by a reactive tissue response. We postulate that ...
A UV–Visible–NIR fluorescence lifetime imaging microscope for laser-based biological sensing with picosecond resolution
(Springer-Verlag, 2003-05)
This article describes the design and characterization of a wide-field, time-domain fluorescence lifetime imaging microscopy (FLIM) system developed for picosecond time-resolved biological imaging. The system consists of ...
Clinically feasible reconstruction of 3D whole-body PET/CT data using blurred anatomical labels
(IOP Publishing Ltd, 2002-01-01)
We present the results of utilizing aligned anatomical information from CT images to locally adjust image smoothness during the reconstruction of three-dimensional (3D) whole-body positron emission tomography (PET) data. ...
