Current modeling of endothelial cell mechanics does not account for the network of F-actin that permeates the
cytoplasm. This network, the distributed cytoplasmic structural actin (DCSA), extends from apical to basal membranes, with
frequent attachments. Stress fibers are intercalated within…

A continuum model describing the steady-state actin dynamics of the cytoskeleton of living cells Has been
developed to aid in the interpretation of photoactivated fluorescence experiments. In a simplified cell geometry, the model
assumes uniform concentrations of cytosolic and cytoskeletal…

We have studied nine laser transitions in Ba vapor at wavelengths
between 1.13 and 3.05 micrometer. Three of these laser lines have not
been reported previously. The relative intensities of the four strongest
transitions (1.13, 1.50, 2.55, and 2.92 micrometer)…

It is shown experimentally that free shear flows can be substantially altered through direct control of the large coherent vortices present in the flow.

The action of adenine nucleotides on vascular endothelial cells is apparently mediated by the local flow conditions. Because
nucleotides are sequentially degraded from ATP - ADP - AMP -- adenosine by ecto-enzymes at the endothelial surface, it has been
hypothesized…

The analogous techniques of photoactivation of fluorescence (PAF) and fluorescence recovery after photobleaching
(FRAP) have been applied previously to the study of actin dynamics in living cells. Traditionally, separate
experiments estimate the mobility of actin monomer or the lifetime of…

Polymethine laser dyes which fluoresce in the near infrared in
organic solvents generally exhibit poor temporal stability at room
temperature. Two typical laser-pumped polymethine dyes in aqueous
solutions containing nonionic surfactants are investigated. Temporal
stability was improved 20-fold, as compared…

Presented in this paper is a robust control scheme for
controlling systems with time delays. The scheme is based on the Smith
controller and the LQG/LTR (Linear Quadratic Gaussian/Loop Transfer
Recovery) methodology. The methodology is applicable to undenvater
vehicle systems…

A matrix method for mooring system analysis is
extended to address the dynamic response of towed underwater
systems. Key tools are equivalent linearization and small perturbation
theory, and a pitching towfish model. Two examples of
application of the technique are…
