observations of the “ water fountain ” IRAS 16552 − 3050
We present Very Large Array (VLA) observations of the water maser emission towards IRAS 16552-3050. The maser emission shows a velocity spread of ≃ 170 km s, and a bipolar distribution with a separation between the red and blueshifted groups of≃ 0.08. These observations and the likely post-AGB nature of the source indicate that IRAS 16552-3050 can be considered as a member of the “water fountai...

متن کاملThe turbo-fountain
Reliable wireless broadcast with asynchronous data access based on fountain coding is investigated. We review the traditional problem formalisation for fountain codes operating on erasure channels, and we generalise the problem formalisation to more general channels. We introduce a novel type of rateless codes based on the Turbo Principle: the Turbo-Fountain. The Turbo-Fountain is able to consi...
متن کاملTAp63: The fountain of youth
The mechanisms controlling organismal aging have yet to be clearly defined. In our recent paper [1], we revealed thatTAp63, the p53 family member, is a critical gene in preventing organismal aging by controlling the maintenance of dermal and epidermal precursor and stem cells critical for wound healing and hair growth. In the absence of TAp63, dermal stem cells (skin-derived precursors or SKPs)...
