Telomere shortening In wildlife Telomere > In wildlife In contrast, the available information shows no sex differences in telomere length across vertebrates. Phylogeny and life history traits such as body size or the pace of life can also affect telomere dynamics.

IP multicast Secure multicast IP_multicast > Secure multicast The sender of a multicast packet does not know the potential receivers; therefore, the creation of pair-wise encryption keys (one for each receiver) is impossible. The sender must encrypt packets using a shared key that all the legitimate receivers use to de...

Fourier synthesis Discrete-time Fourier transform (DTFT) Fourier_synthesis > Variants of Fourier analysis > Discrete-time Fourier transform (DTFT) A sufficient condition for perfect recovery is that the non-zero portion of S(f) be confined to a known frequency interval of width 1/T. When that interval is , the applicab...

Find-me signals Humans Find-me_signals > In Apoptosis > Humans Humans turn over billions of cells as a part of normal bodily processes every day, which correlates with about 1 million cells being replaced per second. The ultimate goal of the body's intrinsic cell death mechanisms is to efficiently and asymptomatically ...

Metric System Summary Metric_unit A unit derived from the base units is used for expressing quantities of dimensions that can be derived from the base dimensions of the system—e.g., the square metre is the derived unit for area, which is derived from length. These derived units are coherent, which means that they invol...
