Recent traffic analyses from various packet networks have shown the existence of long-range dependence in bursty traffic. In evaluating its impact on queuing performance, earlier investigations have noted how the presence of long-range dependence, or a high value of the Hurst parameter <i>H</i>, is often associated with surprisingly large queue sizes. As a(More)

This paper studies some data link layer error control go-back-N ARQ protocols suitable for point-to-multipoint communication over broadcast channels where data are delivered to the destinations in the order they are sent. We study a series of protocols differing in the way that the sender usea the outcomes of the previous transmissions. The protocols have(More)
We present a case of a 51-year-old man with panhypopituarism who developed clinically mild encephalopathy with a lesion in the splenium of the corpus callosum, in the setting of acute influenza A infection. The patient's initial presentation included hypernatraemia due to pre-existing iatrogenic central diabetes insipidus. Despite adequate treatment of(More)
Type VI collagen (COL6) forms a microfibrillar network often associated with type I collagen and constitutes a major component of the desmoplastic reaction in pancreatic ductal adenocarcinoma (PDA). We have demonstrated recently that the α3 chain of COL6, COL6A3, is highly expressed in PDA tissue and undergoes tumor-specific alternative splicing. In this(More)
This paper studies data link layer error control protocols suitable for point-to-multipoint communication where data are delivered to the destinations in the order they are sent. We study a series of adaptive protocols differing in the way that the sender uses the outcomes of the previous transmissions. The protocols are based on the go-back--\schemes(More)
