We have derived a broad, deterministic model of the steady-state actin cycle that includes its major regulatory
mechanisms. Ours is the first model to solve the complete nucleotide profile within filaments, a feature that determines the
dynamics and geometry of actin networks at the leading edges of motile cells, and one that has challenged investigators
developing models to interpret steady-state experiments. We arrived at the nucleotide profile through analytic and numerical
approaches that completely agree. Our model reproduces behaviors seen in numerous experiments with purified proteins, but
allows a detailed inspection of the concentrations and fluxes that might exist in these experiments. These inspections provide

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) vary with buffer gas pressure,
suggesting that collisional deexcitation of the 6p 1^P_1 state occurs
at higher pressure and is the main mechanism populating the upper
states of the 2.55 and 2.33 micrometer lines.

The lasing efficiencies and photochemical stabilities of laser
dyes useful in the 710-1080-nm spectral region have been investigated
using a Q-switched ruby laser pumping source. The measured bleaching
rates P defined as the probability of irreversible decomposition of a dye
molecule per absorbed photon, varied from <= 1 exp-5 to 3 exp-4
for the different dye-solvent combinations investigated. Broad-band
lasing efficiencies (the ratios of dye laser output to ruby radiation
input) ranged from 4 to 43 percent. Shifts of wavelength tuning range
with variations in solvent, dye concentration, and dye laser cavity
geometry are reported.

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 to organic solutions, with no
significant changes in laser-pumping threshold or tuning range.

The imminent balloting of the draft DICOM 3.0 module
on ultrasound represents a major step forward in the
progress of digital storage formats for
echocardiography. In this paper, we discuss a software
suite soon to be released into the public domain for
reading, parsing and verifying DICOM 3.0 ultrasonic
objects. The software is designed to allow the user to
verify that a Jle consisting of digital ultrasound data,
claiming DlCOM 3.0 conformance, does in fact adhere
to the standard. A graphical user-interface for the
software suite is also provided, allowing the playback of
cin& mode images in real-time on standard computer
hardware, and across a TCP/IP network.
