Miniaturized auto-focusing VCM actuator with zero holding current
Psang Dain Lin

Auto-focusing actuators in camera phones have had to reduce their profile without sacrificing performance due to the requirements of current consumer electronic products. In this study, a novel holding structure and electromagnetic characteristics of a Voice Coil Motor (VCM) actuator modified according to the previous design [4] is proposed to reduce its power consumption. It includes a VCM, …

Synthesis, Structure and Photophysical Properties of Highly Substituted 8,8a-Dihydrocyclopenta[a]indenes
Yao-Ting Wu

Alkynes contain one or more carboncarbon triple bonds and belong to the class of unsaturated hydrocarbons. They are important building blocks in common organic molecules, natural products and organic conducting materials. The π nature of acetylenes can be easily activated and allows for various reaction types, particularly for CC bond formation. For example, acetylene, the simplest member of …

Phase-separated Si nanoclusters from Si oxide matrix grown by laser-assisted chemical vapor deposition
Ching-Ting Lee

Recently, silicon-based materials are now playing an important role in microelectronic devices. But their applications in optical integrated circuits are severely handicapped by the indirect band gap properties of bulk crystalline Si (c-Si). In order to achieve integration with other Si-based electronic circuits and optical integrated circuits, substantial efforts have been undertaken to …

VEGF-A/VEGFR-2 signaling leading to CREB phosphorylation is a shared pathway underlying the protective effect of preconditioning on neurons and endothelial cells.
Chao-Ching Huang

Hypoxic-ischemia (HI) encephalopathy is a major cause of neonatal mortality and neurological disabilities in childhood. A new approach to studying treatment for neonatal HI encephalopathy is investigating states of tolerance. Although neurons are the cellular target of preconditioning, ischemic tolerance occurring on vascular cells might also contribute greatly to neuroprotection. …
