Individual droplets can be isolated within microfluidic systems by use of an immiscible carrier layer. This type of two phase systems, often termed "digital microfluidics", find wide ranging applications in chemical synthesis and analysis. To conduct on-chip biochemical analysis, a key step is to be able to merge droplets selectively in order to initiate the required reactions. In this paper, a...

In the 1990's, a large number of hospitals and medical practices have merged to form integrated healthcare networks (IHN's). The nature of an IHN creates new demands for information management, and also imposes new constraints on information systems for the network. Important tradeoffs must be made between homogeneity and flexibility, central and distributed governance, and access and confident...

Techniques for video object motion analysis, behaviour recognition and event detection are becoming increasingly important with the rapid increase in demand for and deployment of video surveillance systems. Motion trajectories provide rich spatiotemporal information about an object’s activity. This paper presents a novel technique for classification of motion activity and anomaly detection usin...

We use the large catalogues of haloes available for the Millennium Simulation to test whether recently merged haloes exhibit stronger large-scale clustering than other haloes of the same mass. This effect could help to understand the very strong clustering of quasars at high redshift. However, we find no statistically significant excess bias for recently merged haloes over the redshift range 2 ...

useable, e-commerce applications require systematic development, including data integration. Traditionally, the integration proceeds in a bottom-up way. This article discusses the problems and proposes a top-down approach to overcome some of the problems. A combined yo-yo approach aims to exploit both strategies' benefits. E-commerce is an application domain in which integrating Web data from d...

We have demonstrated a novel type of superconducting transmon qubit in which Josephson junction has been engineered to act as its own parallel shunt capacitor. This merged-element (MET) potentially offers smaller footprint and simpler fabrication than conventional transmons. Because it concentrates the electromagnetic energy inside junction, reduces relative electric field participation from ot...

This paper is aimed at providing a uniform framework for reasoning about beliefs of multiple agents and their fusion. In the first part of the paper, we develop logics for reasoning about cautiously merged beliefs of agents with different degrees of reliability. The logics are obtained by combining the multi-agent epistemic logic and multi-sources reasoning systems. Every ordering for the relia...
