State and Regional Hydrologic Information Systems - presentation by David Maidment & David Tarboton

submitted by: cmatiuk
Maidment & Tarboton: The CUAHSI Hydrologic Information System enables water data to be delivered through the internet in a common language called WaterML, which describes time series of observations measured at a point locations for quantities such as streamflow, water quality, climate and groundwater conditions. Collections of water observations data from a variety of sources are stored in the CUAHSI Observations Data Model and published in WaterML as CUAHSI water data web services....

From a Queen Song to a Better Music Search Engine

submitted by: ucsandiego
At a recent IEEE technology conference, UC San Diego electrical engineers presented a solution to their problem with the song “Bohemian Rhapsody,”—and it’s not that they don’t like this hit from the band Queen. The electrical engineers’ issue with “Bohemian Rhapsody” is that it is too heterogeneous... http://ucsdnews.ucsd.edu/newsrel/students/05-09Barrington.asp

Aggregation of mouse fetal cells on a NAN nanofiber insert.

submitted by: Arjumond
Visualization of the formation of multiple small punctate areas of aggregation across the surface of a NAN nanofiber insert. Early passage mouse fetal cells in suspension were injected into a Sykes-Moore chamber containing a NAN nanofiber insert. The cells attached to the nanofiber insert and were observed for seven days using time-lapse videomicrography. Cell cultures growing on NAN nanofiber inserts behave differently from such behavior on SAN nanofiber inserts, both of which provide a...

Time lapse videomicrography of the life cycle of Dictostelium

submitted by: Arjumond
Distinct stages of Dictyostelium discoideum life cycle can be seen. As the video starts there is a wave of bacterial growth across the agar. From the implantation site of the spores, you can see the myxamoeba migrating out consuming the E.coli. As the E.coli is consumed you can see a clearing in the agar after which the myxamoeba using chemical signaling form multicellular slugs. The slugs can be seen migrating across the field of view, with the formation of a sorocarp in the upper right...

Aggregation of mouse fetal cells on a SAN nanofiber insert.

submitted by: Arjumond
Visualization of the formation of one large amorphous cell aggregate migrating across the surface of a SAN nanofiber insert. Early passage mouse fetal cells in suspension were injected into a Sykes-Moore chamber containing a SAN nanofiber insert. The cells attached to the nanofiber insert and were observed for seven days using time-lapse videomicrography. Aggregation of a cell monoloayer into one large globular cell aggregate which migrates across the field of view, as observed with 10X...

Robotic Mouse Makes Maze Debut at UC San Diego

submitted by: ucsandiego
An intrepid group of University of California, San Diego undergraduates has designed and build a robotic mouse from scratch. The electrical engineering and computer science undergraduates from the Jacobs School of Engineering also wrote the software to teach the robot to solve a maze. The team unveiled their mouse at the IEEE Region 6 Southwest Area Spring Meeting on Saturday, April 25th, held at UC San Diego. http://ucsdnews.ucsd.edu/newsrel/students/05-09MicroMouse.asp
