  2. Numeric precision in Microsoft Excel - Wikipedia

    en.wikipedia.org/wiki/Numeric_precision_in...

    Excel maintains 15 figures in its numbers, but they are not always accurate; mathematically, the bottom line should be the same as the top line, in 'fp-math' the step '1 + 1/9000' leads to a rounding up as the first bit of the 14 bit tail '10111000110010' of the mantissa falling off the table when adding 1 is a '1', this up-rounding is not undone when subtracting the 1 again, since there is no ...

  3. Error correction code - Wikipedia

    en.wikipedia.org/wiki/Error_correction_code

    The two main categories of ECC codes are block codes and convolutional codes. Block codes work on fixed-size blocks (packets) of bits or symbols of predetermined size. Practical block codes can generally be hard-decoded in polynomial time to their block length. Convolutional codes work on bit or symbol streams of arbitrary length.

  4. Cell cycle withdrawal - Wikipedia

    en.wikipedia.org/wiki/Cell_cycle_withdrawal

    This allows such cells to have continuous division. [7] Some other cells do not have the mechanism of cell cycle withdrawal because they don't even contain the function of cell division. Red blood cells, for example, do not contain genetic material when mature, and hence will not carry out cell cycle or its withdrawal. [8]

  5. Mitotic inhibitor - Wikipedia

    en.wikipedia.org/wiki/Mitotic_inhibitor

    This interrupts cell division, usually during the mitosis (M) phase of the cell cycle when two sets of fully formed chromosomes are supposed to separate into daughter cells. [2] [3] Tubulin binding molecules have generated significant interest after the introduction of the taxanes into clinical oncology and the general use of the vinca alkaloids.

  6. Cyclic redundancy check - Wikipedia

    en.wikipedia.org/wiki/Cyclic_redundancy_check

    The advantage of choosing a primitive polynomial as the generator for a CRC code is that the resulting code has maximal total block length in the sense that all 1-bit errors within that block length have different remainders (also called syndromes) and therefore, since the remainder is a linear function of the block, the code can detect all 2 ...

  7. Cell synchronization - Wikipedia

    en.wikipedia.org/wiki/Cell_synchronization

    Cell synchronization is a process by which cells in a culture at different stages of the cell cycle are brought to the same phase. Cell synchrony is a vital process in the study of cells progressing through the cell cycle as it allows population-wide data to be collected rather than relying solely on single-cell experiments.

  8. Block code - Wikipedia

    en.wikipedia.org/wiki/Block_code

    The term block code may also refer to any error-correcting code that acts on a block of bits of input data to produce bits of output data (,). Consequently, the block coder is a memoryless device. Under this definition codes such as turbo codes , terminated convolutional codes and other iteratively decodable codes (turbo-like codes) would also ...

  9. G2-M DNA damage checkpoint - Wikipedia

    en.wikipedia.org/wiki/G2-M_DNA_damage_checkpoint

    Cells with a defective G 2-M checkpoint will undergo apoptosis or death after cell division if they enter the M phase before repairing their DNA. [1] The defining biochemical feature of this checkpoint is the activation of M-phase cyclin-CDK complexes, which phosphorylate proteins that promote spindle assembly and bring the cell to metaphase.
