Moblie Concrete Research Lab, 2004

A new, state-of-the-art mobile lab has recently been launched from the PCC Center at Iowa State University to bring high-tech concrete materials and concrete pavement testing capabilities to the field. The Mobile Concrete Research Lab has been custom built and fully outfitted with equipment capable of performing a comprehensive suite of tests.

Time-resolved lanthanide luminescence for lab-on-a-chip detection of biomarkers on cancerous tissues.

PDMS-based microfluidic devices combined with lanthanide-based immunocomplexes have been successfully tested for the multiplex detection of biomarkers on cancerous tissues, revealing an enhanced sensitivity compared to classical organic dyes.

One, two, (three), infinity: Newspaper and lab beauty-contest experiments

"Beauty-contest" is a game in which participants have to choose, typically, a number in [0,100], the winner being the person whose number is closest to a proportion of the average of all chosen numbers. We describe and analyze Beauty-contest experiments run in newspapers in UK, Spain, and Germany and find stable patterns of behavior across them, despite the uncontrollability of these experiments. These results are then compared with lab experiments involving undergraduates and game theorists as subjects, in what must be one of the largest empirical corroborations of interactive behavior ever tried. We claim that all observed behavior, across a wide variety of treatments and subject pools, can be interpretedas iterative reasoning. Level-1 reasoning, Level-2 reasoning and Level-3 reasoning are commonly observed in all the samples, while the equilibrium choice (Level-Maximum reasoning) is only prominently chosen by newspaper readers and theorists. The results show the empirical power of experiments run with large subject-pools, and open the door for more experimental work performed on the rich platform offered by newspapers and magazines.

Bridge Deck Expansion Assembly on Jefferson Street in Ottumwa, HR-505C, 1990

The objective of this research was to evaluate two experimental D.S. Brown, Type SL450 and one D.S. Brown, Type SL750 expansion assemblies to identify possible construction problems and to determine the long term performances. These joints were installed in Wapello County on Jefferson Street viaduct in Ottumwa, Iowa. Visual inspections were made yearly. There is an indication that there may be a slow leakage at all three joints. The joint assemblies have performed well.
