XML streams are online, continuous, distributed, high throughput sources of information. For streams carrying a significant intellectual and/or industrial value, proving ownership over pirated copies is a requirement for data producers. Watermarking is a known technique for hiding a copyright mark in a digital document, in a resilient manner. While such methods already exist for numerical strea...

We focus on headwater streams originating in the mountainous terrain of northern temperate rain forests. These streams rapidly descend from gradients greater than 20% to less than 5% in U-shaped glacial valleys. We use a set of studies on headwater streams in southeast Alaska to define headwater stream catchments, link physical and biological processes, and describe their significance within wa...

In this paper, we present our design for a high performance prefetcher, which exploits various localities in both local cache-miss streams (misses generated from the same instruction) and the global cache-miss address stream (the misses from different instructions). Besides the stride and context localities that have been exploited in previous work, we identify new data localities and incorpora...

The number of applications involving ionic liquids has dramatically increased in the past few years, and their production and use in a large scale will inevitably lead to their dispersion into water streams (either by wastewater disposal or accidental leakage). Studies on the removal and recovery of ionic liquids from wastewater streams are therefore of crucial importance, yet particularly scar...

In a superimposed unicast and multicast transmission system, one layer of Successive Interference Cancellation (SIC) is required at each receiver to remove the multicast stream before decoding the unicast stream. In this paper, we show that a linearly-precoded Rate-Splitting (RS) strategy at the transmitter can efficiently exploit this existing SIC receiver architecture. By splitting the unicas...

BACKGROUND: Water quality improvement is potentially an important function of wetlands. Mechanisms that occur in wetlands, such as sedimentation, filtration, adsorption, precipitation, decomposition, and uptake and metabolism, can act to reduce concentrations of problematic water quality constituents flowing into wetlands. Similarly, streams, ponds, and lakes can act as natural treatment system...

The auditory system appears to begin listening to an input with a basis toward hearing the input as a single stream, but it gradually accumulates evidence over a period of seconds which may lead to the input's being split into substreams. Several seconds of silence or of unpatterned noise slowly remove the bias of the mechanism in favor of these streams. The effects were demonstrated in experim...

Today we are faced with an increasing variety of networks and end systems. The resulting heterogeneous environment imposes new challenges on communication support for multimedia and collaborative applications. AMnet is an approach that provides multipoint communication support for large-scale groups with heterogeneous receivers. Active network nodes are used to deliver data streams with user-ta...
