Introducing the visual language and process of design to beginning architectural engineering students
(American Society for Engineering Education, 2006-01-01)
The "Introduction to Architecture" course for freshmen architecture and architectural engineering students has been offered every fall semester since 1995. The fundamental course goals are to introduce the process of design, ...
Characterization of alginate lyase from Pseudomonas syringae pv. Syringae
(American Society for Microbiology, 2000-11)
The gene encoding alginate lyase (algL) in Pseudomonas syringae pv. syringae was cloned, sequenced, and overexpressed in Escherichia coli. Alginate lyase activity was optimal when the pH was 7.0 and when assays were conducted ...
Identification of rat lung-prominent genes by a parallel DNA microarray hybridization
(BioMed Central, 2006-03-13)
Background: The comparison of organ transcriptomes is an important strategy for understanding gene functions. In the present study, we attempted to identify lung-prominent genes by comparing the normal transcriptomes of ...
Langevin analysis of fundamental noise limits in coherent anti-Stokes Raman spectroscopy
(American Physical Society, 2005-01-04)
We use a Langevin approach to analyze the quantum noise in coherent anti-Stokes Raman spectroscopy in several experimental scenarios: with continuous-wave input fields acting simultaneously and with fast sequential pulsed ...
Cloning, characterization and expression analysis of porcine microRNAs
(BioMed Central, 2009-02-05)
Background: MicroRNAs (miRNAs) are small ~22-nt regulatory RNAs that can silence target genes, by blocking their protein production or degrading the mRNAs. Pig is an important animal in the agriculture industry because of ...
THz parallel plate photonic waveguides
(AIP Publishing, 2005-07-26)
We have observed narrowband transmission or rejection in the frequency spectra of THz pulses transmitted through air-spaced parallel plate photonic waveguides. These waveguides have one of the metal plates covered by a ...
Molecular characterization of slow leaf-rusting resistance in wheat
(Crop Science Society of America, 2005-02-23)
Slow leaf-rusting resistance in wheat (Triticum aestivum L) is gaining acceptance as a breeding objective because of its durability in comparison with race-specific resistance. CI 13227 was previously reported to provide ...
Photon-photon correlations as a probe of vacuum-induced coherence effects
(American Physical Society, 2008-03-27)
We show how the effects of vacuum-induced coherence can be realized by studying photon-photon correlation in the pi-polarized fluorescence in the j=1/2 to j=1/2 transition. These effects should thus be observable in ...
Intrinsic current-voltage properties of nanowires with four-probe scanning tunneling microscopy: A conductance transition of ZnO nanowire
(AIP Publishing, 2006-07-24)
We report intrinsic current-voltage properties of ZnO nanowire measured by a four-tip scanning tunneling microscopy (F-STM). It is found that after bending the nanowire with the F-STM the conductance is reduced by about ...
Optical tunneling of single-cycle terahertz bandwidth pulses
(American Physical Society, 2001-08-27)
We report time-domain measurements with subpicosecond resolution of optical tunneling of terahertz electromagnetic pulses undergoing frustrated total internal reflection. Measurements of the transmitted electromagnetic ...
