Enhancement of Microfluidic Mixing Using Harmonic and Chaotic Electric Fields
Chieh-Li Chen

Species mixing is important to numerous microfluidic systems, such as micro total analysis systems (μ-TAS) or lab-on-a-chip (LOC) devices. Rapid and effective mixing enables rapid processing and analysis of species. However, fast and efficient mixing in microfluidic systems was a challenge. The smallness of microfluidic devices constrains fluid flow to the low Reynolds number regime, such that …

Long-Term Operations of Polymeric Thin-Film Transistors: Electric Field-Induced Intrachain Order and Charge Transport Enhancements of Conjugated Poly(3-hexylthiophene)
Horng-Long Cheng

Polymeric thin-film transistors (TFTs) hold the promise of flexible displays and inexpensive organic electronics. For real applications, it is important to understand any changes in microstructural and electronic properties of polymer semiconductors during the operating cycle and over the lifetimes of devices. In this study, we show an improvement in microstructural and charge transport properties …

Aquatic birnavirus induces necrotic cell death via mitochondria-mediated caspases pathway
Jiann-Ruey Hong

Infectious pancreatic necrosis virus (IPNV) is a fish pathogen and the prototype of Birnaviridae virus family.  A quatic birnaviruses had caused the serious mortality in aquaculture industry.  Therefore, to study the pathogenesis mechanism of virus infection and how to prevent infected by IPNV is very important issue.

Apoptosis/necrosis is controlled at the mitochondrial level by …

Presynaptic mechanisms underlying cannabinoid inhibition of excitatory synaptic transmission in rat striatal neurons
Kuei-Sen Hsu

Cannabinoids, the principal psychoactive constituents of marijuana, have a wide range of effects on the central nervous system, including loss of concentration, impairment of memory, enhancement of sensory perception, and mild euphoria. Despite mediating these psychotropic effects in brain, cannabinoids can be clinically effective analgesics, useful in the treatment of glaucoma, bronchial asthma, …
