Invasive insects and fungal pathogens have triggered numerous declines in ecologically important tree species in the forests of eastern North America. Although now functionally extinct in many ecosystems, these tree species have been able to persist through sprouting or...

Abstract Asymmetric hollow fibre membrane modules coupled with a concentrated alkaline solution were investigated both experimentally and theoretically for the removal of H2S from gas streams. Each of the modules used consisted of a bundle of hollow fibres having an ult...

Incentive mechanisms for crowdsourcing are designed to incentivize financially self-interested workers to generate and report high-quality labels. Existing mechanisms are often developed as one-shot static solutions, assuming a certain level of knowledge about worker mo...

China is among one of the oldest civilizations in the world. The massive land mass of China also means that the Chinese people are subject to weather extremes as well as topographical variety in a country which cuts across alpine heights, treacherous deserts, lush valle...

Dengue virus (DENV) is the most prevalent mosquito-borne virus pathogen in humans. There is currently no antiviral therapeutic or widely available vaccine against dengue infection. The DENV RNA genome is methylated on its 5′ cap by its NS5 protein. DENV bearing a single...

Abstract The superior colliculus (SC) is thought to have an inhibitory effect on arousal (and hence activity) in rats when light is present. d-Amphetamine is believed to suppress this inhibition of the SC on arousal. The present study investigated the electrophysiologic...

The quasi-normally-off operation of AlGaN/GaN HEMTs was realized using strain engineering. The dual-layer silicon nitride (SiNx) stressors applied compression to the gate region in devices, and the introduced compression translated to piezoelectric polarization charges ...

DC-DC converter is required to supply various DC voltage levels from battery to logic devices for most of the portable systems, such as cellular phone, portable DVD, CD player, etc. As the energy capacity of a battery is usually very limited, DC-DC converter with high e...

Research on transnational care work has tended to focus on the migration of women for either domestic work or nursing, and the two bodies of work have remained largely separate. In developed countries such as Singapore, however, the high level of female labour force par...

Abstract Polyphenols, the ubiquitous secondary metabolites of plants, are an important part of human diet and are essential for plant functions. They have attracted considerable interest due to their important biological activities as well as intriguing chemical and phy...
