Collagen gels are widely used in experiments on cell mechanics because they mimic the extracellular matrix in physiological conditions. Collagen gels are often characterized by their bulk rheology; however, variations in the collagen fiber microstructure and cell adhesion forces cause the mechanical properties to be inhomogeneous at the cellular scale....
The data is a JSON format file containing the position, velocity, and fish identifier data for 300 golden shiners in a shallow (depth of 4.5 to 5 cm) rectangular water tank (2.1 by 1.2 meters). There are 5000 individual frames (samples of position and velocity) corresponding to video taken at...
Tuna management in the Western and Central Pacific (WCP) is complicated given the dynamic and sometimes conflicting interests of participating countries and actors exploiting the tuna resource in the region. Pacific Island Countries (PICs) through the Fisheries Forum Agency (FFA) and the Parties to the Nauru Agreement (PNA) have developed a...
We use the NCEP/NCAR Reanalysis (NCEP)
and the MPI/ECHAM5 general circulation model to drive
the RegCM3 regional climate model to assess the ability of
the models to reproduce the spatiotemporal aspects of the
Pacific-North American teleconnection (PNA) pattern.
Composite anomalies of the NCEP-driven RegCM3 simulations
for 1982–2000 indicate that the...
Knowledge of cloud and precipitation formation processes remains
incomplete, yet global precipitation is predominantly produced by
clouds containing the ice phase. Ice first forms in clouds warmer
than −36 °C on particles termed ice nuclei. We combine observations
from field studies over a 14-year period, from a variety of
locations...
In this thesis I present the results of a comprehensive assessment of the Pacific-North American (PNA) teleconnection pattern in general circulation models (GCMs) and a regional climate model (RCM). The PNA teleconnection pattern is a quasi-stationary wave field over the North Pacific and North America that has long been recognized...
In the Pacific Ocean, the total catch of skipjack tuna has been increasing rapidly. Then, eight of Polynesian, Melanesian, and Micronesian countries (PNA countries) have concluded a cooperative management of tuna fisheries. Although those countries do not catch a large amount by themselves, the main migrating area is included in...
Tuna fisheries provides an important source of income, foreign exchange and employment for many Pacific Island States. It is also seen as a major avenue for industrial development by most Pacific Island States. The Law of the Sea Convention, while recognising the rights of coastal States to manage and develop...
The Western Central Pacific Fishery Commission (WCPFC) was inaugurated in 2004 after a preparatory process which commenced in 1996. Scientific advice is that skipjack stocks are in good condition, but bigeye and yellowfin stocks are being exploited too heavily and reductions of effort are needed to avoid overfishing. Compared to...
A high-spectral resolution laser-excited molecular fluorescence
system was developed that utilizes a pulsed supersonic expansion to
simplify the fluorescence excitation spectra of large, gas-phase
aromatic molecules diluted in an excess of a monatomic gas. A
microcomputer was used to control and synchronize the instrumental
components, which included a Chromatix CMX-4...
