Anomalous effective viscoelastic, thermoelastic, dielectric, and piezoelectric properties of negative-stiffness composites and their stability
Yun-Che Wang

Ferroelastic materials exhibit two different shapes of energy landscape; one contains only a single energy minimum, and the other two energy minima. From high temperature to low temperature, the solid-solid phase transition of the ferroelastic materials changes their microstructures from high to low symmetrical ones. The single energy minimum before transformation becomes a energy maximum point, …

Master equation approach to transient quantum transport in nanostructures incorporating initial correlations
Wei-Min Zhang

Quantum transport incorporating initial correlations in nanostructures is a long-standing problem in mesoscopic physics. In the past two decades, investigations of quantum transport have been mainly focused on steady-state phenomena, where initial correlations are not essential due to memory loss. Recent experimental developments allow one to measure transient quantum transport in various nano …

Global Oct4 target gene analysis reveals novel downstream PTEN and TNC genes required for drug-resistance and metastasis in lung cancer
Yi-Ching Wang

Oct4, encoded by POU5F1, is one of the key transcription factors for maintaining pluripotency of embryonic stem cells (ESCs). Although the genome-wide binding profile of Oct4 in ESCs has been reported, little is known about those in somatic cancer cells or tumor-initiating cells (TICs). To explore the underlying mechanism of Oct4 in driving somatic cancer into TIC-like states, we conducted …

Investigation of Barrier Property of Copper Manganese Alloy on Ruthenium
Wen-Hsi Lee

In this study, we investigated the properties of CuMn/Ru stack as barrier materials for next-generation Cu interconnects. CuMn has been proposed as a self-forming barrier, which generates a thin barrier layer between CuMn and SiO2 after annealing at 450 °C [1-4]. However, to achieve high thermal stability and low resistivity, the annealing time, temperature and the concentration of Mn …
