  2. Phase 10 - Wikipedia

    Phase 10 is a card game created in 1982 by Kenneth Johnson and sold by Mattel, which purchased the rights from Fundex Games in 2010. [1] Phase 10 is based on a variant of rummy known as contract rummy. It consists of a special deck equivalent to two regular decks of cards, and can be played by two to six people.

  3. Phase variation - Wikipedia

    en.wikipedia.org/wiki/Phase_variation

    In biology, phase variation is a method for dealing with rapidly varying environments without requiring random mutation. It involves the variation of protein expression, frequently in an on-off fashion, within different parts of a bacterial population. As such the phenotype can switch at frequencies that are much higher (sometimes >1%) than ...

  4. Phasevarion - Wikipedia

    en.wikipedia.org/wiki/Phasevarion

    However, in many bacterial pathogens, mod genes contain simple sequence repeats (SSRs), and the associated restriction enzyme encoding gene (res) is inactive. In these organisms the DNA methyltransferase phase varies between two states (ON or OFF) by variation in the number of SSRs in the mod gene. [9] Multiple different mod genes have been ...

  5. Antigenic variation - Wikipedia

    en.wikipedia.org/wiki/Antigenic_variation

    Antigenic variation can result from gene conversion, [1] site-specific DNA inversions, [2] hypermutation, [3] or recombination of sequence cassettes. [4] The result is that even a clonal population of pathogens expresses a heterogeneous phenotype. [5] Many of the proteins known to show antigenic or phase variation are related to virulence. [6]

  6. Phase modulation - Wikipedia

    en.wikipedia.org/wiki/Phase_modulation

    Phase modulation (PM) is a modulation pattern for conditioning communication signals for transmission. It encodes a message signal as variations in the instantaneous phase of a carrier wave. Phase modulation is one of the two principal forms of angle modulation, together with frequency modulation.

    Conversely, a phase reversal or phase inversion implies a 180-degree phase shift. [ 2 ] When the phase difference φ ( t ) {\displaystyle \varphi (t)} is a quarter of turn (a right angle, +90° = π/2 or −90° = 270° = −π/2 = 3π/2 ), sinusoidal signals are sometimes said to be in quadrature , e.g., in-phase and quadrature components of a ...

    5-10% will be from carbohydrates — that's around 20-50 grams of net carbs per day. Says Susie, while there are benefits to the keto diet, such as weight loss and blood sugar and insulin control ...

  9. Phase transition - Wikipedia

    en.wikipedia.org/wiki/Phase_transition

    In physics, chemistry, and other related fields like biology, a phase transition (or phase change) is the physical process of transition between one state of a medium and another. Commonly the term is used to refer to changes among the basic states of matter : solid , liquid , and gas , and in rare cases, plasma .
