Ellagic acid has been demonstrated to inhibit the growth of several types of cancer cells. However, whether it sensitizes human colorectal carcinoma cells to 5-fluorouracil, has not yet been investigated. Colorectal carcinoma HT-29, Colo 320DM, SW480 and LoVo cells were treated with ellagic acid (2.5-25 μg/ml) and 5-fluorouracil (5-25 μM) alone and in(More)
This paper proposes a systematic method of system identification and control of a proton exchange membrane (PEM) fuel cell. This fuel cell can be used for low-power communication devices involving complex electrochemical reactions of nonlinear and time-varying dynamic properties. From a system point of view, the dynamic model of PEM fuel cell is reduced to(More)
This paper develops a multivariable robust controller for a proton exchange membrane fuel cell (PEMFC) system. To give a perspective of the system, a PEMFC can be simplified as a two-input-two-output model, where the inputs are air and hydrogen flow rates, while the outputs are cell voltage and current. By fixing the output resistance, we aim to control the(More)
Keywords: Electrochemical exfoliation Bilayer graphene sheets Graphene ink Transparent electrodes Flexible displays a b s t r a c t Graphene is a highly promising candidate to replace oxide-based conducting materials for fabrication of transparent electrodes used in flexible displays and electronic devices. However, so far an appropriate method is still not(More)
We will describe a dynamic federated autonomic networking system1 for the testing of netcentric systems across organizations. Using a suite of policy-based management software tools, our system can provide netcentric missions with self-configuring, self-debugging, self-healing, and self-protecting capabilities across end-to-end coalition networks. The(More)
BACKGROUND Hypoxia has been shown to facilitate tumor progression. Hypoxia-regulated microRNA-210 (miR-210) may play an important role in carcinogenesis and tumor progression. In this study, we evaluated the clinical significance of miR-210 expression in upper tract urothelial carcinoma (UTUC). METHODS Eighty-three UTUC patients participated in this(More)
In order to facilitate a robust object oriented definition of policy exchange interfaces across semi-autonomous domains within an enterprise, a protocol neutral approach to describing the information exchanged is followed. This protocol neutral approach makes use of the Unified Modeling Language (UML) to describe information classes and their properties as(More)
