The current review provides an overview on the palliative, combined, neoadjuvant, bridging, and symptomatic indications of transarterial chemoembolization (TACE) in patients with hepatocellular carcinoma (HCC). It is based on an analysis of the current literature and the experience of the authors on the topic. Chemoembolization combines the infusion of(More)

The problem of single-group multiple-antenna multicasting is considered, where common information should be sent to a large number of users. The multiple-antenna transmitter is assumed to accurately know the instantaneous downlink channel state information (CSI) for all users, and our objective is to design the beamformer complex weights to minimize the(More)
In this paper, we consider an asynchronous relay network where different relaying paths are subject to different propagation delays thus causing inter-symbol-interference (ISI) at the destination. To eliminate such an ISI, orthogonal frequency division multiplexing (OFDM) is deployed at the source and destination but not at the relays. In fact each relay(More)
We develop a mesh simplification strategy that preserves angle bounds. Preliminary results for a sample of planar Delaunay meshes are then presented. We demonstrate significant improvements of Triangle output, in terms of the number of Steiner points needed for a required angle bound, specially for large bounds where Triangle is known to possibly perform(More)
The NewsStand system enables the use of a map query interface to retrieve news articles associated with the principal locations that they mention collected as a result of monitoring the output of over 10,000 RSS news feeds, made available within minutes of publication. NewsStand has been enhanced to allow using the map query interface to access other(More)
We consider the problem of distributed beamforming in amplify-and-forward (AF) relay networks for single-group multicasting, where a single transmitter sends common information symbols to a group of users via cooperating relays. The objective is to design a computationally efficient beamforming scheme to minimize the total transmitted power at the relays(More)
