Multifunctional pH-Sensitive Magnetic Nanoparticles for Simultaneous Imaging, Sensing and Targeted Intracellular Anticancer Drug Delivery
Dong-Hwang Chen

Targeted drug delivery systems which interact with intracellular components or events such as pH change are becoming increasingly important for controlled and triggered release of drugs. In the last decade nanotechnology and nanofabrication have significantly impacted the field of drug delivery. Enabled by their size and supramolecular structures, nanoparticles promise to be particularly capable …

Temperature-Dependent Characteristics of a Pseudomorphic High Electron Mobility Transistor (PHEMT) with Graded Triple Delta-Doped Sheets
Wen-Chau Liu

Recently, the prosperous designs of various compound semiconductor devices, such as the pseudomorphic high electron mobility transistors (PHEMTs), heterostructure field-effect transistors (HFETs), and heterojunction bipolar transistors (HBTs) have been widely applied in monolithic microwave integrated circuits (MMICs). Also, doped-channel field-effect transistors (DCFETs), due to the specific …

Bile acid exposure up-regulates tuberous sclerosis complex 1/mammalian target of rapamycin pathway in Barrett's-associated esophageal adenocarcinoma
Chia-Jui Yen

Chronic gastroesophageal reflux disease which consists of the reflux of gastric contents including bile acid and gastric acid into to the lower esophagus can lead to the inflammation of esophagus. Chronic gastroesophageal reflux disease develops the pathologic transformation of normal squamous esophagus epithelium into metaplastic intestinal, like epithelium, Barrett's epithelium which is the …

Performance of a Guideway Seismic Isolator with Magnetic Springs for Precision Machinery
George C. Yao

Earthquake damage to non-structural components in buildings with precision equipment and industrial machinery is a major loss for any company. However, the fragility of precision machinery is usually considered proprietary information. In Taiwan, for example, semiconductor production and non-structural component loss at high tech facilities in Hsinchu's Science Based Industrial Park was estimated …
