Speckle noise caused by interference of electromagnetic waves complicates Synthetic aperture radar (SAR) images to be interpreted and further practical application, therefore reducing speckle noise and preserving more detailed information are indispensable tasks in pre-processing. In this paper, a new insitu single-pointed (ISPW) method based on wavelet(More)
Velvet antler of deer (VAD) is a commonly-used kidney-Yang supplementing traditional Chinese medication. According to the heart-kidney-related theory, heart Yang originates in kidney Yang and heart failure due to heart Yang deficiency can be treated by tonifying kidney Yang. In this study, we investigated therapeutic effects of VAD on cardiac functions in(More)
Bacterial response to surface topography during biofilm formation was studied using 5 μm tall line patterns of poly (dimethylsiloxane) (PDMS). Escherichia coli cells attached on top of protruding line patterns were found to align more perpendicularly to the orientation of line patterns when the pattern narrowed. Consistently, cell cluster formation per unit(More)
Bacterial biofilms are a major cause of chronic infections and biofouling; however, effective removal of established biofilms remains challenging. Here we report a new strategy for biofilm control using biocompatible shape memory polymers with defined surface topography. These surfaces can both prevent bacterial adhesion and remove established biofilms upon(More)
2013 i Acknowledgements In the long process of completing this thesis, I would like to express my sincere appreciation to my adviser and committee chair, Professor Annemarie Schneider, who has the attitude and the substance of a true geographer. Her devotion to research and attention to detail continuously pushed me to produce better work. Without her(More)
Forests are important to nutrient cycling, hydrology, climate and aesthetics in urban ecosystems. Effective forest management in urban environments requires detailed data on the spatial distribution and structure of urban forests, but the lidar which are best for mapping the complexity of these forests are often unavailable or prohibitively expensive for(More)
