Synthesis of Microwave Planar Dual-Band Filters
Chih-Ming Tsai

In recent years, the fast growing cellular phones and wireless local area network (WLAN) provide the convenient and ubiquitous wireless communications, and the dual-band systems could help to enhance the reliability. For example, a dual-band cellular phone could automatically select the most unobstructed channel between those at 900 MHz and 1800 MHz under the GSM system. ...

Effect of Oxidizer on the Galvanic Behavior of Cu/Ta Coupling during Chemical-Mechanical Polishing
Wen-Ta Tsai

Introduction
To meet the requirement of global planarization, chemical-mechanical polishing (CMP) has emerged as a critical technique in Cu metallization process. Although Cu CMP exhibits some advantages over the conventional techniques, such as dry-etching, etc., there still exist some unfavorable factors affecting the CMP efficiency. ...

A spray flame propagating in a non-adiabatic duct with varying cross-sectional area
Shuhn-Shyurng Hou

Owing to the successful introduction of large activation energy asymptotics in combustion, great progress has been made in understanding the physics of a flame. As a result, numerous investigations have been devoted to asymptotic theories of steady deflagrations with sprays, heat losses (conduction or radiation), stretch and a Lewis number other than unity. ...

Dual roles of arsenic in cancer
Huei-Sheng Huang

Arsenic is a well-documented environmental carcinogen. Epidemiological survey strongly implicates that exposure to arsenic in drinking water will induce neurotoxicity, liver injury, diabetes, peripheral vascular disease (known as blackfoot disease), and increase risks of cancer of skin, bladder, kidney, lung and colon. ...

Significance and Causes of Unusual High-Field-Strength Element Fractionation in Eclogite from Sulu Metamorphic Terrane
Huai-Jen Yang

The composition of bulk silicate Earth (mantle and crust) has been estimated from three general consensuses. (1) The Sun, planets and meteorites of the solar system are related in composition since they were very probably derived via the same set of nucleosynthetic events. ...
