This study characterized cancer stem cells (CSCs) in hepatocellular carcinoma (HCC) cell
lines, tumor specimens, and blood samples. The CD90 + cells, but not the CD90 − cells, from …

The pharmacology and clinical application of traditional Chinese medicine has been extensively
documented. We have used an in vitro model system, PC12 cells, to demonstrate the …

A design of a high-force-output large-deflection parallel-plate electrostatically actuated
microgripper is described. This design uses polysilicon as a structural material and may be …

Continuous growth in demand for optical network capacity and the sudden maturation of
WDM technologies have fueled the development of long-haul optical network systems that …

This article presents the first study on the magnitude of tracking error and the determinants of
tracking errors using the daily figures of the Exchange Traded Funds (ETFs) traded in Hong …

A gas-phase, room-temperature, plasmaless isotropic etching system has been used for
bulk and thin film silicon etching. A computer controlled multi-chambered etcher is used to …

Xenon difluoride is a gas phase, room temperature, isotropic silicon etchant with extremely
high selectivity to many materials commonly used in microelectromechancial systems, …

The clinical experience gathered throughout the years has raised awareness of primary
immunodeficiency diseases (PIDD). T cell receptor excision circles (TREC) and kappa-deleting …
