Wind Speed And Seismic Motion Data Analysis, Margarita Vidrio

STAR Program Research Presentations

The Laser Interferometer Gravitational Wave Observatory (LIGO) was developed to exploit Einstein's prediction of gravitational waves to develop a new way to study the universe. Gravitational waves are detected by observing changes less than 1/10000 of the diameter of a proton in the distances between hanging mirrors that are four kilometers apart within two perpendicular evacuated tubes. These changes in distances between mirrors are produced by gravitational waves from large masses in space, such as colliding black holes. Many factors affect the sensitivity of the interferometer. LIGO’s Physical Environment Monitoring subsystem (PEM) is one method of both eliminating noise and …

Mother Convict Cichlids Inflict More Bites Upon An Intruder In Hot Temperatures, Jesse L. Heckendorf

STAR Program Research Presentations

Convict cichlids (Archocentrus nigrofasciatus) have developed to be extremely good parents by protecting their brood. Parental care leads to aggressive biting, chasing, and gill flaring to intimidate known predators. In this experiment, we show that environmental factors, such as the changing of temperature in this case, affect a female convict cichlid’s aggression toward caring for her offspring when an intruder is introduced. Females attack more in warmer water.

Jellyfish Identification And Quantification In The San Francisco Estuary, Amalia Borson, Lindsay L. Sullivan, Wim Kimmerer

STAR Program Research Presentations

As potential predators and competitors of plankton-eating fish, jellyfish have the potential to negatively impact fish populations. Jellyfish were collected weekly with plankton tows from the RombergTiburonCenterpier in Tiburon, CA. Since some jellyfish were too small to identify, one tow was collected and preserved to record abundances, and a second tow was collected to rear jellyfish until distinguishing characteristics were visible enough for identification. Jellyfish in the preserved tows were then identified, measured, and counted, and their abundance (number m^-3) was calculated. Jellyfish from the second tows were reared in plastic buckets that were lightly bubbled using aquarium …

STAR Program Research Presentations

The research is testing the limits of detection and multiplexing with the use of three pathogens with the machine created from Luminex called Magpix. The pathogens are Salmonella enterica, Listeria monocytogenes, and Escherichia Coli O157. The gene that is being focused on for each pathogen is invA for Salmonella, hlyA for listeria, and hlyA for Escherichia Coli. In this research, we started with prepared probes that were attached to the magnetic microsphere beads. Then we extracted and amplify the DNA. Furthermore, the probes were combined to the amplified DNA and used this in Magpix which gave a corresponding MFI value.

Juxtaposing Nasa’S Aeronet Aod With Carb Pm Data Over The San Joaquin Valley To Facilitate Multi-Angle Imaging Spectroradiometer (Misr) Pm Pollution Research, John Kanemoto

STAR Program Research Presentations

Airborne particulate matter (PM) has been shown to increase the risk for asthma, chronic bronchitis, cardiopulmonary complications, and respiratory cell membrane damage/infection/leakage. PM levels are currently analyzed from two perspectives: stationary land-based monitoring (LBM) sites and total Aerosol Optical Depth (AOD) atmospheric column measurements. Both perspectives often leave miles of space between measuring locations and will have a continually increasing cost from introducing/maintaining sites. The Multi-angle Imaging SpectroRadiometer (MISR) satellite team hopes to begin investigating/archiving PM levels comprehensively via inputting MISR AOD measurements into a function/model which predicts the amount of ground level PM.

In the future, multivariable spatial correlations …

The Abundance And Distribution Of Gelatinous Zooplankton In The San Francisco Estuary, Amalia Borson, Lindsay Sullivan, Wim Kimmerer

STAR Program Research Presentations

Until recently, gelatinous zooplankton were not considered important components of the San Francisco Estuary (SFE) foodweb. However, anecdotal evidence, ongoing research, and a few published reports and papers suggest an increase in their abundance over the last 10 to 20 years. Of particular interests are three species of introduced hydromedusae (Blackfordia virginica, Maeotias marginata, and Moerisia lyonsi). All three inhabit the fresh to brackish regions of the estuary, including Suisun Bay, the channels of Suisun Marsh, and the western Sacramento-San Joaquin Delta, and are seasonally abundant throughout late summer and fall. As a result, they overlap …

Agent Based Modeling As An Educational Tool, Jonathan H. Fuller, Rodger Johnson, Vic Castillo

STAR Program Research Presentations

Motivation is a key element in high school education. One way to improve motivation and provide content, while helping address critical thinking and problem solving skills, is to have students build and study agent based models in the classroom. This activity visually connects concepts with their applied mathematical representation. “Engaging students in constructing [models] may provide a bridge between frequently disconnected conceptual and mathematical forms of knowledge.” (Levy and Wilensky, 2011)
