  2. Estrous synchronization - Wikipedia

    en.wikipedia.org/wiki/Estrous_synchronization

    Estrous synchronisation is the process of targeting female mammals to come to heat within a short time frame (36 to 96 hours). This is achieved through the use of one or more hormones. Methods to improve our ability to synchronize the reproductive process and result in the ‘timed insemination’ without the detection of heat have been developed.

  3. Estrous cycle - Wikipedia

    en.wikipedia.org/wiki/Estrous_cycle

    Much estrous control in cattle is for the purpose of synchronization, a practice or set of practices most often used by cattle farmers to control the timing and duration of estrus in large herds. [4] There is variation between the available methods of cattle estrous synchronization.

  4. Menstrual synchrony - Wikipedia

    en.wikipedia.org/wiki/Menstrual_synchrony

    Menstrual synchrony, also called the McClintock effect, [1] or the Wellesley effect, [2] is a contested process whereby women who begin living together in close proximity would experience their menstrual cycle onsets (the onset of menstruation or menses) becoming more synchronized together in time than when previously living apart.

  5. Flehmen response - Wikipedia

    en.wikipedia.org/wiki/Flehmen_response

    The flehmen response (/ ˈ f l eɪ m ən /; from German flehmen, to bare the upper teeth, and Upper Saxon German flemmen, to look spiteful), also called the flehmen position, flehmen reaction, flehmen grimace, flehming, or flehmening, is a behavior in which an animal curls back its upper lip exposing its front teeth, inhales with the nostrils usually closed, and then often holds this position ...

  6. System of linear equations - Wikipedia

    en.wikipedia.org/wiki/System_of_linear_equations

    A solution of a linear system is an assignment of values to the variables ,, …, such that each of the equations is satisfied. The set of all possible solutions is called the solution set. [5] A linear system may behave in any one of three possible ways: The system has infinitely many solutions.

  7. Pickering emulsion - Wikipedia

    en.wikipedia.org/wiki/Pickering_emulsion

    The most common type of Ramsden emulsions are oil-in-water emulsions due to the hydrophilicity of most organic particles. One example of a Ramsden-stabilized emulsion is homogenized milk. The milk protein units are adsorbed at the surface of the milk fat globules and act as surfactants. The casein replaces the milkfat globule membrane, which is ...

  8. Lorenz system - Wikipedia

    en.wikipedia.org/wiki/Lorenz_system

    A sample solution in the Lorenz attractor when ρ = 28, σ = 10, and β = ⁠ 8 / 3 ⁠ The Lorenz system is a system of ordinary differential equations first studied by mathematician and meteorologist Edward Lorenz. It is notable for having chaotic solutions for certain parameter values and initial conditions.

  9. Linear dynamical system - Wikipedia

    en.wikipedia.org/wiki/Linear_dynamical_system

    Linear dynamical systems can be solved exactly, in contrast to most nonlinear ones. Occasionally, a nonlinear system can be solved exactly by a change of variables to a linear system. Moreover, the solutions of (almost) any nonlinear system can be well-approximated by an equivalent linear system near its fixed points. Hence, understanding ...
