Tunable grating based on stressed liquid crystal
Andy Ying-Guey Fuh

It is known that a typical grating can diffract an incident light into various-order beams. Gratings based on liquid crystal (LC) have attracted considerable interest owing to their high birefringence and sensitivity to an applied field, and possess considerable potential for application in displays, photonics and optical communications. In this paper, we report a new LC grating using the newly developed stressed liquid crystals (SLCs). …

Product design evaluation model of child car seat using gray relational analysis
Hsin-Hsi Lai

The purpose of this study aims to search for the comfort relations of child car seats by performing an experiment of physiological measures, and applying a scientific effective algorithm to build the product design evaluation model for designing optimal child car seats. The fundamental theory of the new product design evaluation (abbreviated as PDE ) model is based on an artificial intelligent technique, …

Selective Liquid-Phase Oxidation of InGaAs and Application to Metal–Oxide-  Semiconductor InAlAs/InGaAs Metamorphic HEMT Without Gate Recess
Yeong-Her Wang

A selective, low cost, low temperature (30–70˚C), liquid phase oxidation of InGaAs using metal or photoresist as the mask has been proposed, and the oxide film composition and some process issues are also evaluated. Finally, the application of InAlAs/InGaAs MOS-MHEMT without gate recess has also been demonstrated. Without gate recessing, the gate oxide is obtained directly by oxidizing the InGaAs capping layer in a growth solution. …

Oct-3/4 expression reflects tumor progression and regulates motility of bladder cancer cells
Chao-Liang Wu

Cancer and embryonic stem cells exhibit similar behavior, including immortal, undifferentiated, and invasive activities. Here we demonstrate that in clinical samples bladder tumors with intense expression of stem cell marker Oct-3/4 (also known as POU5F1) are associated with further disease progression, greater metastasis, and shorter cancer-related survival compared to those with moderate and …
