Rapid startup of microbial fuel cells (MFCs) and other bioreactors is desirable when treating wastewaters. The startup time with unamended wastewater (118 h) was similar to that obtained by adding acetate or fumarate (110-115 h), and less than that with glucose (181 h) or Fe(III) (353 h). Initial current production took longer when phosphate buffer was added, with startup times increasing with ...

Elastic cloud applications rely on fast virtual machine (VM) startup, e.g. when scaling out for handling increased workload. While there have been recent studies into the VM startup time in clouds, the effects of the VM image (VMI) disk size and its contents are little understood. To fill this gap, we present a detailed study of these factors on Amazon EC2. Based on our findings, we developed a...

I develop a continuous-time model of reputation in which a privatelyinformed seller, such as a startup, tries to court a forward-looking buyer, such as a venture capitalist (VC). The VC learns gradually about the startup’s quality, high or low, through exogenous news and can adopt at any time. The startup can exit or privately upgrade its quality at any time. I discover two novel kinds of reput...

Land transportation over the past two centuries has experienced astonishing advancement. Up until 1860s, it took more than six months to get from East Coast West of United States. Today, may take only three days by automobile. We are even considering flying cars and there air-taxi startup companies that have announced going public <xref ref-type="bibr" rid="ref1" xmlns:mml="http://www.w3.org/19...
