We introduce LT codes, the first rateless erasure codes that are very efficient as the data length grows.

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)...

When a positively buoyant vertical fluid jet directed downwards from its source impinges on a horizontal flat surface, the resulting flow is termed an “impinging fountain”. These flows arise in a number of practical situations, for example, in gas metal arc welding (GMAW). Developing a description of this flow presents the researcher with a number of challenges and forms the motivation for this...

1839 yılında Sultan Abdülmecid’in ihya ettiği Halid Ağa Çeşmesi’nin adı değiştirilerek

The highand intermediate-velocity interstellar clouds (HVCs/IVCs) are tracers of energetic processes in and around the Milky Way. Clouds with near-solar metallicity about 1 kpc above the disk trace the circulation of material between disk and halo (the Galactic fountain). TheMagellanic Stream consists of gas tidally extracted from the SMC, tracing the dark matter potential of the Milky Way. Sev...

OBJECTIVE The aim of this study was determination of the level of water contamination in fountains in Toruń, Poland. METHODS The studies were conducted at monthly intervals from May - September 2009, and consisted in the determination of the number of heterotrophic bacteria capable of growing at a temperature of 22 and 37°C (PN-ISO 6222), as well as the number of coliform bacteria (PN-75/C-04...
