In this paper, a new forward error correction (FEC) protocol is proposed for point-to-multipoint satellite links. Link-layer error control protocols in point-to-multipoint satellite links impose several problems such as unreliability and receiver-heterogeneity. To resolve the problem of heterogeneous error rates at different receivers, the proposed scheme exploits multiple multicast channels to...

Recent progress of computer and network technologies makes it possible to store and retrieve a large volume of multimedia data in many applications. In such applications, indexing for retrieving multimedia data efficiently plays a important role. Depending on the media type, multimedia data shows distinct characteristics and requires different approach to handle. In this paper, we propose a fas...

This paper presents a new approach for tunes similarity calculation based on repetitions. Information about repetitions in tunes is important since repetitions make very significant impression to listener. We are providing a way to describe tunes in descriptors which contain frequency information about repetitions of tunes. Frequency information is retrieved by means of a relatively new signal ...

The reference to ethnicity in the 2012 National Suicide Prevention Strategy for England (1) is mainly with regard to promoting mental health in Black and Minority Ethnic (BME) groups. However, there is little detailed information about any specific strategy to reduce suicide rates in BME groups. The Suicide Prevention Strategy and Action Plan for Northern Ireland has only one brief reference re...

The cognitive relationship between lyrics and tunes in song is currently under debate, with some researchers arguing that lyrics and tunes are represented as separate components, while others suggest that they are processed in integration. The present study addressed this issue by means of a functional magnetic resonance adaptation paradigm during passive listening to unfamiliar songs. The repe...

Musics, like languages and genes, evolve through a process of transmission, variation, and selection. Evolution of musical tune families has been studied qualitatively for over a century, but quantitative analysis has been hampered by an inability to objectively distinguish between musical similarities that are due to chance and those that are due to descent from a common ancestor. Here we prop...

Multiple structural, biochemical and in vivo studies have solidified the role that histone acetyltransferases (HATs) play in regulation of the p53 pathway. 1 HATs are known to modulate p53 functions in many ways, from regulating its stability to promoting acetyla-tion-dependent interactions with DnA as well as various co-factors and chromatin modi-fiers. 1 Of these, p300, CBP, PCAF and Tip60 ar...
