Infrastructure-as-a-Service (IaaS) cloud platforms rent resources, in the form of virtual machines (VMs), under a variety of contract terms that offer different levels of risk and cost. For example, users may acquire VMs in the <i>spot market</i> that are often cheap but entail significant risk, since their price varies over time based on market supply and(More)

BACKGROUND Curcumin inhibits the growth of esophageal cancer cell lines; however, the mechanism of action is not well understood. It is becoming increasingly clear that aberrant activation of Notch signaling has been associated with the development of esophageal cancer. Here, we have determined that curcumin inhibits esophageal cancer growth via a mechanism(More)
Executive Summary Prominent among a number of new techniques with which to image the colon, computed tomographic (CT) colonography is extremely attractive because it is noninva-sive and also relatively simple for patients to undergo. As the technology evolves, it is important that gastroenterolo-gists not only understand the multiple issues surrounding CT(More)
Cloud spot markets enable users to bid for compute resources, such that the cloud platform may revoke them if the market price rises too high. Due to their increased risk, revocable resources in the spot market are often significantly cheaper (by as much as 10&#215;) than the equivalent non-revocable on-demand resources. One way to mitigate spot market risk(More)
—Distributed applications implicitly assume that data center servers are available unless they fail. However, many emerging scenarios are altering this assumption by exposing transient availability, such that servers are available temporarily for an uncertain amount of time. Transient servers are cheaper and more energy-efficient than stable servers with(More)
OBJECTIVE Barrett's esophagus (BE) is transition from squamous to columnar mucosa as a result of gastroesophageal reflux disease (GERD). The role of microRNA during this transition has not been systematically studied. DESIGN For initial screening, total RNA from 5 GERD and 6 BE patients was size fractionated. RNA <70 nucleotides was subjected to SOLiD 3(More)
Cloud providers have begun to allow users to bid for surplus servers on a spot market. These servers are allocated if a user's bid price is higher than their market price and revoked otherwise. Thus, analyzing price data to derive optimal bidding strategies has become a popular research topic. In this paper, we argue that sophisticated bidding strategies do(More)
